Thank you for reaching out.

Please check your subscription once. This could indicate that a subscription within the tenant has lapsed, or that the administrator for the tenant has disabled the application, preventing tokens from being issued for it which resulted in this error.

Hope this clarifies your doubt. Do upvote if you find my answer helpful.
