I'm not entirely sure how to to provide documentation for this crash, and I'm not entirely sure how to exactly prove the crashes are due to minecraft. But at this point I've had dozens of instances weird freeze behavior that ONLY occurs when minecraft is running, sometimes within five minutes of starting the game, sometimes after playing for a while. Sorry if my descriptions are bad, but I haven't had a way to check for the source of the problem because every time it arises I need to restart my system. But at this point I'm pretty confident this is only occurring when the game is running. I don't think this was happening when my game was still on 1.13, so it might be related to something inside 1.13.1.
The freeze behavior:
I will be playing minecraft seemingly just fine, and just without warning both screens on my two monitor display go black, and the last ~2 seconds of audio I was hearing loop on my speakers for a few seconds and then go silent. With the screens black the system is completely stopped and I have to restart the system.
Normally when I come back to the game, the save file still works fine although some progress is lost from the game not saving some recent events. But there was one instance so far where the save actually got corrupted from the freeze, but luckily I had a backup. At this point I've had this freeze at least 25 times.
The apparent freeze conditions:
I haven't been able to connect a specific set of actions or events in the game to the freezing, however it seems that the game is just fine with the player not moving at all. I can leave the game running overnight and come back in the morning with no freezes pretty reliably. But if I play the game walking around and looking around, I can bet on a freeze occurring within an hour or two. My last freeze actually happened within 5 minutes of getting back into the game from a freeze before that, which took a couple hours to occur.

Right, so I've attached the only two crash reports from this month that were in the crash logs. But like I said, this is a total computer freeze. So I'm not sure the system is getting a chance to write a log at all. There's only two crash reports from this month in there, but like I said, probably more than 25 instances of this specific kind of crash very recently. I also added my launcher log though so hopefully that shows something.
These crash reports might not reflect this current problem. I had reported a bug previously that made the game crash from a void json file in 1.13, but the game would crash and not freeze the whole system. Just trying to show all the stuff I have for the crashes. So I'm not sure the crash reports will show whats happening in my current issue.
Just an update.
I just played the game a bit for the first time since creating this error report. My desktop computer has been able to run stable and run for multiple days now without problems, but I fired up minecraft and played for about 30 minutes and experienced the same characteristic computer wide freeze that turns the screen completely black and stops any audio that requires me to reset my computer to use it again.
I've also double checked my crash reports and again no crash report was generated, probably from the entire computer freezing and not allowing a report to be written. I've also attached a new copy of my launcher log file since it was probably modified from playing again.
Just got my system up and running again after another crash during the game. Was walking around and building some redstone. This was probably around 50 minutes maybe a bit over an hour of playing. Again, no complete computer freezes at any time between creating the bug report and now, aside from two freeze crashes from two sessions so far of somewhat short gameplay.
Just trying to show why I think the problem I'm experiencing is connected to the game.
And just got my system up and running again from another freeze crash.
Very frequent system wide freeze crashes only during the game when I can demo days of constant good computer functionality without the game. I just haven't been able to connect consistent behavior to it.
Is there anything I can do to get more info from the game while I play it? Since crash reports aren't being generated and I can't connect a behavior to the crash I don't know how to provide any actual useful information about the problem.
Situations for today's specific freeze crashes to hopefully provide a little more info on a hard to measure problem:
1st crash - Clearing and replanting farm crops one plot at a time, freeze occurred when refilling one of the plots. So lots of items were being dropped and picked up in waves.
2nd crash - After the 1st crash I decided to try changing some of the graphics settings, which I had tried before but just to have as a test case. I changed graphics to fancy, reduced chunk rendering to 10, and set particles to limited. I was in the middle of laying redstone dust for a less than 10 block volume device that wasn't running a clock signal so the redstone wasn't updating or anything. The process was breaking half of a village house down to put the redstone components inside and halfway through the process the freeze occurred.
3rd crash - I was clearing my items to get ready to close the game and finish fishing for crashes. And after putting all of my stuff in chests I walked out on top of my house to jump off the highest point cuz why not, and mid jump the computer freeze crashed and needed a reboot.
I hope this helps figure out the problem. I think my computers otherwise pretty good stability except when running the game at least shows an association to the game. Not sure if its my java or not since I know that acts has acted weird on my computer at times. But certainly nothing like this. I'll also attach my game save as well. Not sure if the game just really dislikes how many banners and item frames I'm using or not.
Hey guys, itsyaboy big-money-minecrash here coming to you with another update.
So I tried playing at different villages in the same save that was freezing and also playing on a different save that was created in 1.13 that is a lone island in an ocean. I think after playing in different areas and in a different save I think there's something about my home base that is causing the freeze. It seems that when I play the game at other villages or in my other save, I don't have the freeze issues. However if I play at my home base, rather consistently still, within one or two hours I get freezes. I've even had experiences where using an elytra to fly to my home base the computer does the weird crash seemingly as soon as the chunk is loaded in. The only main difference I can tell between all the villages I've run the game with and my home village is I have extensive use of banners and item frames. I don't know if this is the exact cause, but those are the main different types of blocks that exist in my home village chunk that don't exist in the other villages or in my other save.
I'll add a screenshot of my maps to the issue to show the areas I've tested in and I'll re add my game save
I've added a screenshot of my maps in my world affected by the bug. The red region is my home village where I experience the crashes and the red is a long duration tested working area. Crashes appear to occur roughly in the red area within only a couple hours, and the green area has been tested working after running for longer than 3 hours as well as leaving the game running idle and coming back to play many hours later. Same longevity tests have been done in my other save file I'm providing without having the freeze crash, but again my home area in the red in the screenshot is pretty consistent for me after more than an hour of play.
Here is a link to my broken save and another save file I tested that seemed to work fine as well.

The problem appeared to stop after one of the beta versions prior to the 1.14 release, but I just checked using 1.14.3 pre-release 2 and it doesn't seem like the problem is happening.
Thank you for your report!
However, we will need you to attach the crash report.
We do not have enough information to find the cause of this issue.
Please attach the crash report file found in
[.minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder]here.If you cannot find a crash report, please attach the full launcher log file found in
[.minecraft/launcher_log.txt|http://hopper.minecraft.net/help/guides/minecraft-logs/].This issue may be temporarily resolved as Awaiting Response. Once the report is attached, the issue will be reopened automatically.
