Unable to Sign In with SSO

I signed up for Zoom using Google SSO. The business email I used was hosted by Google workspace at the time and have now switched to a different provider. This means I can no longer sign in using Google SSO. The password reset option is not working (no email is triggered). I can't sign in to my Business account with a Pro license (I'm posting on this forum from my personal free account).

How can I remove my SSO login and switch to a password login?
