GitHub Actions has encountered an internal error when running your job

Encountered this error in my workflow today. Re-run multiple times, all failed with same error quickly. (Link to that workflow will be available upon request.)

During the troubleshooting, I tried to re-run the same workflow that passed yesterday, but the re-run is currently being queued for longer-than-usual time.

Neither github incident history nor github status shows any error for today (Apr 7, 2021).

What else do I need to look at?
