After logging into my Microsoft account in the MC launcher and quitting the game, restarting the launcher remembers my MS account and displays it in the account list. Clicking on it, however, causes an error to occur and I'm thrown to the standard "Login with a Microsoft/Mojang account" screen. In the terminal, here is what is outputted:
