I just tested it with a softu2f token and it all seems to work.
If you use any of the other 2FA ones, does it work?

Also, have you tried to remove and re-add the Fido U2F token?

Else we probably need a bit more information like logs etc...

Also, what happens if you create a new account and try to use it there?

Yes, all work except u2f

I tried it and it doesn't work.

A new user can use u2f normally
