Terraform plan shows drift on genesyscloud_routing_queue despite no changes

Running terraform plan keeps showing changes to genesyscloud_routing_queue even though I haven’t touched the config.

module.wfm.genesyscloud_routing_queue.main: Refreshing state... [id=abc-123]
module.wfm.genesyscloud_routing_queue.main: Modifying... [id=abc-123]

It looks like a state lock issue or something cached in the backend. How do I force a refresh or clean this up without breaking the queue?
