Start by inspecting OIDURLQueryComponent.m at line 117 and the OIDTokenRequest.m call at line 297, then trace the token refresh path shown in the crash log. Reproduce the request on iOS 12 or 13 with the listed AppAuth and Google API dependencies. Done means the reported NSInvalidArgumentException no longer occurs, though the issue does not define the expected behavior or a regression test.
