NC31 FIDO2/webauthn stopped working

Since the update to NC 31.0.0.18, passwordless login with webauthn (FIDO2) no longer works for me.
I wanted to log in with my Yubikey, the login screen showed no reaction and the Yubikey did not flash either. I logged in with my password, deleted the configuration on the security page and tried to create the passwordless login with my Yubikey again. But that didn’t work.
An error message appears: “Error, the device could not be registered”. Regardless of whether the Yubiky is plugged into the USB port or not.
In the nextcloud.log (loglevel = 0) you can find:

In the firefox browser console:

I searched Github and help.nextcloud and searched all posts in question, but none solved it.
Does anyone have any advice or ideas?
