Some steps do not start to run

Hi, folks!

I am starting to setup GitHub Actions, but there’s a step that does not start:

I’ve restarted again and again but resulted in the same - it didn’t start.

Does anyone know the reason?

I did nothing especially, but it is running now. Are there variations among macOS machines?

No, not a difference among machines.

It just takes hours to show build logs, so I believe it’s a problem with the log viewer.
