ValueError: invalid null reference in method 'BOARD_ITEM___eq__', argument 2 of type 'BOARD_ITEM const &'

Hi! I'm trying to run the KLE plugin, but whenever I do, I get this message:

Traceback (most recent call last):

For reference, I'm using KiCad 8.0.3 on an M1 mac, running Sonoma 14.5, and I renamed the switches to MX instead of the default SW. I used marbastlib footprints for the hotswap switches and default library footprints for the rest. The layout is a custom version of a 40% keyboard where the bottom row isn't as wide as the rest of the keyboard.

I use manjaro (xfce) and used the plugin with kicad 7 earlier this year. kicad automatically updated to version 8 and now even after a clean and reinstall the plugin won't work (I tested the exact same situation as in kicad 7). I would assume that this is a version mismatch problem? best regards, zegonix
