Most Plugins not working in Glyphs 2.6.7

I only have three Plug-ins installed (Stem Thickness, Reporters, & Layer Whale) but recently my Stem Thickness plugin hasn’t been working. I tried re-installing the Plugins after deleting all the Malware and App Cleaners on my mac, but I couldn’t get it to work. I’ve attached my computer specs to this topic, looking forward to fixing this!!

macOS Big Sur
Version 11.5
iMac (Retina 4K, 21.5-inch, 2019)
Processor 3 GHz 6-Core Intel Core i5
Memory 16 GB 2667 MHz DDR4
Startup Disk Macintosh HD
Graphics Radeon Pro 560X 4 GB

What happens if you run this in the macro panel:

import sys
