HW Fido2 Provider not working in IronFox

It worked great until yesterday, and today, I cannot get it to work. The video below illustrates the problem:

I have tried:

1. Clearing the cache of both HW Fido2 Provider and IronFox
2. Rebooting
3. Installing Key Driver BT Kunizoft
4. Disabling uBlockOrigin, Cookie Banner Blocker and Enhanced Tracking Protection

Any ideas?
