Script Error with Custom Arkhis Preset

When I load an attempt to play a custom Arkhis preset, I get a script error. Oddly, when I created the preset it played fine, but since trying to load it in a new session my CPU usage jumps to over 3000% in Ableton and I only get the script warning flashing. No sound. (Note: my CPU usage isn't actually this high. I checked task manager.)

Also, I never edited the Arkhis script - just the effect chains, but I'll paste the only editable script here. (The other is password locked.)
