If I try to downgrade Firebase SDK to $FirebaseSDKVersion = '9.6.0', works, but the build has a lot of other build fails.

Answer 1

Update or remove mobile_scanner.

The log indicates that mobile_scanner locks in GTMSessionFetcher 1.x which is incompatible with FirebaseAuth 10.22.0 that requires at least GTMSessionFetcher 2.1.
