Hello sai pavan,
Thank you for posting your query here!
Can you please try to navigate to the storage account, then to the container in the Azure portal that holds the state file. The blob will show as ‘Leased’ under the leased state column. Select the state file and hit the ‘break lease’ button.

The lease state on the state file blob should then show as ‘broken’, and you can kick off the next Terraform run.
Or using Terraform you can force the unlock, (get the LockID from the error) e.g.
terraform force-unlock <LockId>
