Urgent, can't reach support. Can't log iin after vanity url change.

I submitted a request, as per the instructions, to change the Vanity URL. The URL was changed, and we updated the Alias in our SSO service, but the login still doesn’t work. Unfortunately, the SSO bypass for the super admin isn’t working either 😞 Now we are completely locked out. I can’t access my super admin account. I can’t contact support via chat because I don’t have a business-level subscription. I can’t submit a new ticket from a personal account because the auto-responder immediately declines it. Phone support is only available during the european time day (or I can’t find the contact info, since I don’t have access to my business account). All I have left is the broken SSO application and an authorized Zoom client on my Mac.I can provide any necessary documents  for my identification, could you please help me urgently restore the service?
