Converting assets fails when running app. (Windows)

Trying to run openage, following these steps. Running on windows and getting the following output.

Any ideas on how to fix it?

Do you know which line in https://github.com/SFTtech/openage/blob/master/openage/convert/processor/export/media_exporter.py triggers this?

Could you recheck in the debugger maybe when this error pops up?

[heinezen]

And what version are you running?
