OSError: cannot open resource

I get this error when I try to run the python script:

The error changes when terminal is in focus:

I had it working few times so I'm not sure what might be causing this error, it seemingly appears out of nowhere. Any idea what might be causing this?

Looks like the font cannot be loaded. Simple first thought: Could it be that you are launching the script from a different directory? The fonts are given as a relative path, so it breaks if you call the Python script from somewhere else.

Oh yes, that was indeed the case. Thank you!
