Game breaks when I join a server/realm

[rustywolf021]

When I load up Minecraft everything seems fine but when I load into a game I get a whole bunch of errors in the chat and when I load out the main menu goes back to the default Minecraft theme.

Using 1.19.1

Errors:

You're using the donor client without a donor account. You must start the game with the donated account, then use the alt manager for non-donor accounts.
