Trying to load the game on the Nintendo switch, tried to uninstall and reinstall same issue

Black screen - takes 5-10 minutes to load to the Mojang red screen, that then takes 15-20 minutes to load - more often than not an error occurs and closes the software. You have to repeat this several times taking nearly 1-2 hours just to try to get on. Then when finally loaded and a world is loaded, it crashes immediately and says error occurred!

This is completely ridiculous! Been happening for the past few updates, now the latest has been installed, it will NOT allow game play. 

Stupid thing is on the switch lite, it loads up immediately no issues but on the normal switch it does not!!! We have both to allow multiplayer on the switch.

Please can you assist resolving this issue!
