Every now and then while I'm playing minecraft I will experience what appears to be server desync followed by a loading bar that will pop up on my screen. The only thing I can do to get rid of the loading bar is to close out my game. When I close it, I get a pop-up that says "Software has closed because and error occured."
Β
I have tried the following troubleshooting methods:
-Restart my switch
-Checking for corrupt data
-Redownloading minecraft on my console
-Checking my internet connection
-Contacting customer support
Β
The issue occurs more frequently in the following situations:
-Loading into a world
-Opening a chest
-Loading big structures
-Entering the netherΒ
-Opening marketplace
Note: It can happen at any time, these are just more common situations
Β
Other details:
-I normally play on a realm and haven't tested the glitch that much on a single player world
-The issue has occured on my switch for over a year, but has been more frequent since the 1.16 update

It doesn't show up in the routers logs. It's not a connection issue, but the type of lag is like desync.

After doing some testing in a single player world, I have concluded that this only happens on a realm or a server. Again, I know that this is not a connection problem on my side.

Thank you for your report!

Brand new game cartridge, installed this morning, same issues. Tried everything you did as well, with the exception that I can't even create a world, it just outright crashes before any actual gameplay.
