Woke up to the same issues listed in the post. I've tried everything including, resetting Microsoft account credentials, ipconfig/dns flushing, manually deleting .minecraft files and reinstalling from Microsoft Store (logged into only Microsoft account). No positive results from any attempts. Still receive account mismatch error and unable to connect to any multiplayer server.
