It crashes randomly and logs you out of your Microsoft account randomly

1. the game crashes randomly online with lots of lag I can move around affect the world but I can’t see what I’m doing and breaking a block with torches/redstone and other blocks that shouldn’t be floating would float and leaving and rejoining fix’s it but then a few minutes later it happens again 

2. logs out of Microsoft randomly kicking me off my friend world ther should be an option to let a friend join without the need for an invite
