@ariG23498 I will also draw your attention to one more factor, which is the fact that the job Deploy / Upload release to TestPyPI (push) is currently failing, but it's okay, it's failing because this particular version of restorers is already available on testpypi. Since we would change the target to the main branch and testpypi to pypi before merging the PR, its fine if it fails for now.
