Hello. I got a new laptop (Windows 11) and have been trying to sign in to my main account for an hour. I can "sign in" with my email and password, and I get the account recovery code in my email. I then enter that, then I am immediately told that my account is "disconnected", even though by all other indications, I am signed in. I mean, I have to be signed in to create this post! I read over other posts, and some of their issues seem to stem from something about their default profile. However, 1) I should still be able to sign in to a non-default profile, 2) I have been able to sign in to a different (student) profile just fine. I have uninstalled and reinstalled FF twice now, with full deletion of profiles etc. And no luck. Other posts have mentioned antivirus software interference, but that doesn't explain why my other (student) profile works fine. Also, when I try to create a recovery key, I am presented with an "unknown error" screen. I have attached a screenshot of that.
