I have four minecraft accounts (all connected to microsoft accounts), and when I attempt to sign into more than three at one time, it seems I have to re-sign into all of the accounts, even ones signed into before the fourth one. This will happen no matter what it, and did not change.
Additionally, after this happens you will sometimes have to restart the launcher. Not always, but sometimes various verification errors will happen attempting to sign into an account if you don't restart it. Inexplicably, one account stayed logged into after these events, but only one time out of 7 or so.
It should be noted this is a system running Windows 11.
