Hello Karthikeyan Sudharsan,
This issue will be resolved by signing in using the tenant-specific Azure portal URL and the tenant ID I have provided over the private messages tab:
https://portal.azure.com/<tenant-ID>
Once you accessed the portal through the tenant-scoped URL, the tenant became active again and you will be able to manage resources without further issues.
And the tenant will be restored successfully.
If this answers your query, do click Accept Answer and Yes, if you have any further queries do let us know.
If you have any other questions, let me know in the “comments” and I would be happy to help you.
