09/05/2025, 3:00 PMI am running into an issue where Deployment Runs are stuck in AwaitingConcurrencySlot even though nothing else is running. I have Concurrency set to 1, and it has always worked as intended before. If I set the Concurrency to 2, they start working again, but that doesn't explain why it thinks something else is already running. Any thoughts?

We had an incident on Sept 4th that might be related. There was a bug preventing deployment concurrency slots from getting released. https://prefect.status.io/
Are you still seeing deployment concurrency slots occupied incorrectly?
