Unable to access Entra Admin Center — tenant provisioning incomplete

I am a single member LLC with a business domain email associated with Google Workspace. I use this as my primary email. I was having issues with Bluetooth and Phone Link connecting to a brand-new Lenovo Yoga Slim 9i running Win 11 and MS 365. I could not complete the Phone Link > QR code went to 403 Forbidden. Bluetooth pairs, connects then disconnects, in a cycle. With Copilot we went to the Entra Admin Center and got an error message AADSTS1600 User account does not exist in tenant." I can see some of my profile behind the dialog box - I see (but cannot access) a Tenant ID and a Primary Domain. Tenant status is Disabled & Sync has never run. I was sent by MS Support to a Entra login page, but it says my domain name isn't in the system. Regular support spent 90 min looking for a bluetooth problem, gave up, transferred me to Business help. After a long hold, I spoke to someone, then we got disconnected in the first couple minutes (he never called back!) and no other way in to get help without being able to sign in (except this). I believe my domain is stuck in a partially provisioned state. I need help verifying domain ownership and completing tenant setup, because I cannot access the admin center to open a support ticket.
