Stuck after clicking "Sign in" / signin fails

After clicking "Sign in" for Google, MS, MS365, it is just stuck there with the button greyed out.

In journalctl, we have:

g_task_return_error: assertion 'error != NULL' failed
GTask goa_oauth2_provider_authorize_uri (source object: <addr>, source tag: <addr>) finalized without ever returning (using g_task_return_*()). This potentially indicates a bug in the program.

Version: 3.52.0-1, Debian testing
