I have a private repo, I created a branch with a workflow, I had a typo in the image name to use. When I pushed my branch the actions tab listed a workflow as:
Untitled workflowSetting up your workflow...
It has been listed that way now for 2 days. I've deleted the branch and it is still there.
Fixed runs-on typo, closed PR and deleted branch. Pushed code on new branch. Worked ... I guess it failed on init of workflow due to wrong virtual environment name?
