After the update to 3.0.22 it appears that EAP authentication is broken.

EAP still works fine. Based on your log snippet, it looks like you are using LEAP.
LEAP was removed in FreeRADIUS 3.0.22. Per the release notes:
- Remove native support for Cisco LEAP. It is insecure, and should not be used. Proxying LEAP is still supported.
