I also get this bug when my server, yet restarting the game fixes it. unfortunately it happens about once a day and is very very annoying. Most likely wont come across it, but if you have IAS or some other in game account logger inner thingy then this comes up all the time since you don't restart your game to get a valid UUID or key or something forget what its called. Basically it forces you to restart your game in 1.19 but not 1.18.2 or earlier as far as I can tell and it drive me insane because I hate rebooting my game because its slow. This is a very inconvenient bug.
You probably know this but a better report is here:
