It looks like 28.x did work, because you report no error message from it.
But 27.2 failed.

27.2 was released in March, 2021.  That is 5 years ago.  I think we
shouldn't break programs that quickly!  I think our tools should
continue to support a program for many more years than that.

Now that I have specific reports, I can discuss them with maintainers.
