older lyx file will not open

[Ivan Werning]

Solved!

Thanks so much Stephan! This was it.

I installed Python by way of...
 xcode-select --install
and I now have Python 3.9.6

I'm sorry I didn't notice the previously reported Ventura issue, as I only
ran into this problem when I was trying to convert a file. Newer files were
loading. So I didn't search for Ventura issues in the forum.

LyX rocks and this mail list rocks. Thanks again Stephan.
