Error 26 & 36 midway through cuts

Hi, I’ve been running into random glitches/feed-stops when cutting, flagged as GRBL error 26 or 36 around line 1790. What’s especially strange is I don’t see the lines showing up in the console within the .nc file. I should note that the attached screenshot is from after trying to resume from line (after the issue first occurred).

I’ve also noticed some errant moves that are not showing up in simulation, could there be something messing with the communication between my laptop and the controller?
