Works for me. Try replugging the key and check that it's not plugged in upside down, then hit Refresh. If it's still not working, try rebooting.

Replugging didn't solve the problem and I am using a USB-C key which can't be plugged in upside down, however rebooting fixed the issue. :)

YubiKey 4 / KeepassXC 2.5.4 / macOS 10.15.4 (Catalina)

After reboot, KeepassXC asked for permission to receive keystroke.
YubiKey backs to normal after granting that permission from Security & Privacy.
