The way I read that error, you are trying to issue an MDI command and for some reason, PP thinks that the machine is in motion. It sounds like something is “stuck” in the software as the flag it uses to determine if there is active motion.
Touchscreen failure would have very little to do with this unless it’s stuck on a UI element that making PP think the machine is moving.
FWIW, 2.8.3 is 5 years old. It may be a bug. Update to something more current. You can revert if necessary.
If you want to replace that touchscreen with a bigger touchscreen
