We received some automatic Paratext error reports from you related to this
and I put one of the reports in our backlog of problems to fix.
The problem is that there must be a project that has an inconsistent
language code between the project settings and the .ldml file in the
project folder. I can’t tell which project this would be happening on - it
may not be the project that you have open since the error is happening when
a list of languages in all projects is being created.
If you look at the .ldml files under you “My Paratext 8 Projects” folder,
you can open the files in notepad an look for ‘<language type=“xyz”’ near
the beginning of the file. If you notice a file when the value in quotes
doesn’t match the name of the file, that is probably the project that is
causing the problem.
Once the project is found, let me know so I can try to see how the problem
occurred.
