Experiencing authentication issues

Hello, I am experiencing an issue in the Azure portal where I am unable to perform any actions or open a support ticket. The error message states that the portal is having difficulties obtaining an authentication token, which may result in a degraded user experience.

Upon further investigation, the error details indicate that the logged-in user is not authorized to fetch tokens for the 'Microsoft_Azure_Support' extension because the user account is not a member of the 'Microsoft Services' tenant. The specific error message is:

"AADSTS50020: User account '{EUII Hidden}' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application 'guid' (Azure Portal) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again."

I would appreciate any assistance in resolving this issue. Thank you.
