In single player worlds, occasionally while breaking blocks, there will be a big lag spike. Then the player and block states revert to their state a few seconds prior. Similar to what I have experienced on servers before, but as I said this is in singleplayer.
I have tried to find a common thing that may be causing this, but as of yet I haven't noticed anything. I have only noticed this in the past couple weeks. Previous to 1.14.4 release I didn't experience it.

The debug files I posted are for the block issue. I captured another lag spike as well in another report, which was when opening a chest. Went to open the chest, and nothing happened, the sound stopped, and then after a second or so it caught up and opened the chest. If there is anything else I can do please let me know.

That sounds like client-side lag, while the block breaking lag is server-side lag.
In the profile, I could not discover anything that's indicating that such lag could occur. Were you able to reproduce the lag, or did it just happen that one time?
The block breaking lag happens sporadically. I had to start/stop the debug a few times before I could get it to happen. I haven't had it happen a 2nd time, but I can try it again until it happens and post those reports. The chest lag happened twice I believe.
I would love to know how lag is happening client-side. As I said before, none of these problems happened until a couple weeks ago, and the only thing that I can think of that was updated, other than Minecraft was Java. If you could direct me somewhere that can help with the client-side, I will explore that alley as well.
If you can manage to reproduce the server-side lag again, please leave a comment.
Client-side lag can have many different causes. If you want to find out, exactly what is causing it, you can use Shift+F3 to enable a cake diagram that shows what takes up how much rendering time.
Sorry this has taken so long, but I have done this again. I will attach the new files, but I am also attaching the latest log file as well. In that file, you can see that root.tick and root.tick.autosave are taking a LONG time, ~6000ms. Now I don't know what is going on, because I upped the allocated RAM to 8GB (I have 32), and my computer is high performance. This shouldn't be happening.
We do not have enough information to find the cause of this issue.
While the lag occurs, please run
/debug start, wait a while and then run/debug stopin order to create a debug profile. Afterwards, run/debug report.If you do not have the permission to run these commands, open your world to LAN and enable cheats. If you're on a server, make sure that you're a server operator in order to execute these commands.
Then, please attach the profile results found in
[minecraft/debug/profile-results-<DATE>.txt|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder], as well as the debug report found in[minecraft/debug/debug-report-<DATE>.zip|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder]here.This issue has been temporarily closed as Awaiting Response. Once the requested information has been delivered, the report will be reopened automatically.
