Mine hasn't acted up as well! I'll play some more and give more feedback in case needed

I realized that when the loading gets stuck like that, when I try to close the game and it crashes it won't work unless I restart the console (Switch)
Not putting it on sleep and turning it back on but shutting it down and starting it again, unless I do that, the game won't work at all 

I never got a warning, I only get this annoying bug that sometimes the menu would never load

I was thinking that this might also be a problem related to the fact that Switch is not optimised for such big save files? Mine is 2GB and maybe it's too big for the console to handle and gets stuck in the process? But I also don't want to be restricted in world size, hopefully Mojang is onto this problem and will resolve it very soon

I tried what Andrew said but in the end I still got this issue even with the automatic upload to cloud turned off, it's really annoying because it's making the game unplayable...

I have the same issue, I added a video I took with this issue if it's alright!

I was able to repair this issue by reinstalling the game, I didn't have any issues with Marketplace since
Maybe it will work for you too!
