Printer pauses randomly at start of print requiring user resume (3.8.0-RC) #2105

I've been experimenting with this gcode for a bit and my printer always pauses during the purge line or just before it for some reason. The screen looks normal, but it will do absolutely nothing until I press the knob on the printer. It's happened twice during the purge, and once before the MMU started the filament load. I've had this issue with 3.7.2 as well but could not get a handle on it at the time.

I finally had it connected to pronterface today which confirmed it as it reported "echo:busy: paused for user" in the console.

I've attached the offending gcode. Please note it's an MMU test print which dumps filament on the right end of the bed as part of an alternate purge system I'm working on.

There are no M0 or M1 codes present, and the fact it's at different places suggests it's not something in the gcode itself causing the pause.
