Ok, some progress. I figure the antivirus was the culprit here although I’m curious why the issue still persists even after disabling the AV. Can you confirm that it was same behavior as before or something like Bug 40679 or Bug 40721 (the ticket itself is private but you can read about the nature of the bug under ‘Known Issues’ in the linked post)?
Tor Browser 11 should work alright with Windows 11.
