That vendor specific EAP method is not really described anywhere and I'm
not sure whether I'd really want to promote it much at this point in
time. Anyway, CONFIG_EAP_UNAUTH_TLS=y is not used with OSEN. The version
of client-unauthenticated TLS for OSEN is selected for the build with

This is the EAP method from CONFIG_HS2=y (the unrelated

Yes, this is the part that is failing.. It looks like you have not
configured the server certificate in hostapd configuration file and
that leaves TLS uninitialized. For any TLS-based EAP methods, the server
will need to have its private key, server certificate, and CA
certificate(s) configured.
