I've noticed after closing Minecraft Bedrock (Xbox One), when i switch to any other game out there that game will not start and I almost always get a Xbox side error message. This issue isnt a issue with my xbox as it doesn't happen with any other game. The only fix for this is to restart the console which is very annoying to every time i want to switch games. To recreate this bug just start minecraft, close Minecraft, then start another game. Some of the time after that game will start or other times it gives you a error. I hope this helps!
