new patch seems to have broken xi on Windows?

[Andrew Cooper]

Hey all, it looks like the new version (even with Oscar's patch 2.41.2) doesn't play nice with <xi>? Maybe a Windows filename issue?

Here's the error: 

Before the update, this was working just fine. Trying it with an empty import file throws the same error.

Your source for the "xi:include" might help.

Would you be willing to downgrade to the previous working version, using `pip install pretext==2.40.2`, and verify that the same files actually work?  I have one idea what might have happened, but I'm not sure I have time in the next week to investigate.  And that should at least get your project working again.

Interesting.  I have not been able to get things to work with python 3.14, so this must be where the issue is.  I'll have to figure out what is going wrong with that soon.

Huh, go figure. I downgraded python to 3.13, reinstalled pretext (2.41.2), and now everything is just fine. I guess it was something about my python installation. Sorry for the trouble!
