Can't login with Firefox

If I use Firefox 103.0.2 to log in to Musicbrainz I get the message “The form you’ve submitted has expired. Please resubmit your request.”
Does anyone know why this happens?
Login with Microsoft-Edge no problem.

I tried it. Deleted all cookies. But doesn’t help.

Has been resolved. Was due to a not clean installation of VM-Ware workstation.
