Based on your description, kindly try these step:
- Open it in an InPrivate/Incognito window.

- Disable VPN, proxy, and browser extensions temporarily.
- Try a different network, such as a mobile hotspot.
If the issue persists, you can reach out Microsoft Support via Customer service phone numbers - Microsoft Support for further assistance.
In addition, there is a faster way to reach out Microsoft Support which is create a new tenant with trial subscription to access and submit a ticket in the Admin Center.
Please sign up for a free trial (new tenant with trial subscription) of Microsoft 365 at this link: Compare All Microsoft 365 Plans | Microsoft. The goal is to create a temporary tenant with a Global Administrator account so that you can sign in to the Microsoft Admin Center. Once connected, you can submit a support ticket directly to Microsoft. Please remember to cancel the trial subscription once your issue is resolved to avoid unwanted charges.
