Can't reset password as it's sending to same email address

Can't reset password as it's sending to same email address

Hello I recently signed up using google to sign in. I am currently using the domain 1upradio.co.uk. The admin account is hayden@1upradio.co.uk. I removed the google account as a way to sign in and now I can't sign in at all, because there isn't a password, and I can't reset the password. What do I do?

I can verify I own the account using a CNAME record or use another account that I do have access to ( liam@1upradio.co.uk)

Thanks!
