changed primary domain in google and cannot log in via SSO now

[radiant widget]

i changed my primary domai in workspace and now i cannot log in to my cloudlfare account because the original email address does not exist anymore.
[email protected]
is renamed in google to [email protected]

If I use my current (changed) google account via SSO to log in to cloudflare a new account is created instead. But I am unable to reach the DNS and verify anything without it. I am stucked. What should I do?

I believe I figured it out. Fortunately, the original domain registrator is using the proper way for SSO - verifying via google id and not email address. Cloudflare should change it because this is insane. They should use internal google ID that is not changing even though the email is different.
