Is there a way to manually reset/clear the cache?

I have a workflow that fails due to some Python-related loading error, but if I remove the julia-actions/cache step in the workflow, it completes successfully, so I suspect that some bad/corrupted package/version of something has been cached. So I want to reset the cache. What is the best way to do this? I guess I could wait a week or something for Github to delete the cache, but I'm impatient!
