Description
Describe the bug
When receiving a runtime warning using the Thread Performance Checker (i.e. "Hang Risk"), clicking on stack traces does not navigate to the source.
Example warning printed to logs:
Thread Performance Checker: Thread running at QOS_CLASS_USER_INITIATED waiting on a lower QoS thread running at QOS_CLASS_DEFAULT. Investigate ways to avoid priority inversions
PID: 92886, TID: 47811725
