Switch system updated today (vers 13.0.0).

Tried my main account that had been having the 45% issue, and it seems to work a LOT better now. I had a small amount of hang time at 45%, somewhere around 30 seconds which after a couple of tests seems consistent. 30 seconds is a lot better than half an hourish! Progress, finally!

Hopefully this isn't an issue that comes back full swing on a different Console update. I'm wary of considering the issue to be fully resolved as I've yet to see Mojang itself release an official fix so it seems more like luck that the Switch update has made Minecraft load up properly again. Can't speak for how it runs on other formats.

Some more observations that I've made, hopefully to help narrow down what's causing the load screen issue-

I've tried running the game on a different Switch user profile (on the same Switch Console)  with no Microsoft/Xbox Live account attached to it and it seems to clear the load screen with no issues, but the MAIN profile I play on, that is connected and signed into an Xbox Live account (along with all my worlds, achievements and item purchases) struggles with this. I don't have any resource packs or mods running.

Perhaps the loadscreen slowdown is getting caused by an issue with Save Cloud data and the cross connectivity with XBox Live? That seems to be the only difference between two profiles I have running.

On a broader but possibly still relevant note, I noticed that playing on a totally fresh file seemed to make other aspects of the game load faster- I don't get the long black screen (different issue, I know), the 45% loadscreen stall and the item shop loads in preview icons properly whilst the MAIN file that I've been getting load screen 45% stall issue on also has slowdowns in other areas so this 45% load screen problem might just be one aspect of a much broader problem to do with the way the game handles save data and profiles that have a substantial game history. This might also explain why uninstalling and re-installing the game hasn't worked for me when I tried loading in my main profile.

The temporary work around would be to play on a different user profile but that is not an acceptable long term solution for this issue as I want to be able to play on my main profile with all my worlds, achievements and item purchases.

Switch version 1.17.11, issue still persists. 

Nick, Mike, I don't think it's either Sonic Studio or RTX cards causing the problems as this long load issue affects multiple platforms including Switch and PS4. Maybe those aren't helping things on PC but the wider problem is the game itself. It stalls on seemingly every format.

On a different note, I don't run resource packs for Bedrock other than whatever the game runs on by default and the only customized things I use in game are the store bought character creator shop items, so I'm not so sure this load issue bug is related to resource packs either. Again, it's possible that they aren't helping but the bug still affects people who aren't running them.

On the newest Switch version of Bedrock, 1.17.10, issue still persists. Black screen that takes a few minutes to get past, then the Mojang Studios screen which takes a long stall at 45%. After a few tries at playing the game it seems to be on average a 25 minute hurdle.

It'd be nice to enjoy the newly added candles in Bedrock but I guess I'll just stare at the Mojang Studios screen all day instead.

I've never played another game that is so broken that it takes the better part of half an hour just to get to the title screen. Fix this.

I'm having a similar issue on Switch as this except the game load stalls at 45% on the Mojang Studios logo. Takes between 15-20 mins for the game to get through whatever content is in the 45% loaded area and progress normally.

Other players consider the Ender Dragon to be the final boss of this game, but for me, it is the Mojang Studios screen.

I attached a screen grab to this report. This is what my Minecraft 1.17 experience looks like now and probably for the forseeable future.

Please fix this as it pretty much kills the game before it even gets to be played.

I have the same issue and it does not appear to matter if I am near one of my villages or in a new quiet location I am working on. I get about 20 minutes in to a session, disconnect and lose progress.

Very frustrating having to chop down the same tree several times.

Oh, I am sorry for that! I was so busy with other stuff and forgot to search for bugs like mine! 

Is there really no solution? 
Buying a new router doesn't work or anything? 
I really want to host a server with my friends, but I can't get around this error. Where can I stay most updated about this bug, here?
