github-actions test-coverage fails on one package but passes on another?

This problem has already been listed here without an answer:

Error in file(con, “r”) : cannot open the connection

Thank you for your reply. Obviously we already read that error and know that it says about the file not exist but we have no control over this folder "private/var/folders" and we can not be deleted or clear this folder in GitHub action. This action execution on GitHub-hosted runners with macOS. How to map this file location?
