CLI version throws error 'Event loop is closed'

[quistuipater]

I'm trying to get NiimPrintX running on macOS Big Sur v11.7.10 on an iMac (Retina, 5K, 27-inch, Late 2014) with a B21 but it crashes. Here's the verbose mode output:

mgibbs@redqueen NiimPrintX % python -m pdb -m NiimPrintX.cli -v info -m b21
