Terraform state lock blocking genesyscloud_routing_queue drift fix

Running terraform plan on our CXone infrastructure. It shows drift on a genesyscloud_routing_queue resource. The queue name changed in the UI, not in code. Trying to fix this with terraform apply but it fails immediately. Getting this error:

Error: Acquiring the state lock was unsuccessful
Timeout was exceeded before acquiring the lock

Checked the remote state backend. No other runs are active. Tried terraform force-unlock with the lock ID. It returns success. Running plan again. Same lock error. The lock ID is different now. Looks like a phantom lock. Verified the AWS DynamoDB table. No stale entries. Restarted the Terraform provider. Nothing. Need to clear the state file manually or is there a API call to force release the lock on the routing queue resource specifically?
