Hi there, Sumit! This is Marc. Thanks for reaching out to the community.
Try waiting 24 hours before signing in again, and when you do, use a stable internet connection and preferably a different browser (try Incognito/InPrivate mode) or device to avoid cached errors. You can also attempt to sign in at https://account.microsoft.com or use the Sign-in Helper tool here: https://support.microsoft.com/account-billing/i-can-t-sign-in-to-my-microsoft-account-475c9b5c-8c25-49f1-9c2d-c64b7072e735. If you still face the issue after waiting, resetting your password may help clear the block.
Let me know how it goes.
Best regards,
