All the belts and pulleys have been tightened. First thing I checked. As I say this issue only cropped up immediately after installing that plug in.
It's not the plugin. The plugin only affects Z. Not X. Besides you removed it. It's a coincidence that it happened at the same time. Something is wrong with your printer.
You can prove it by lowering the jerk and acceleration settings a LOT and it shouldn't lose steps. Try reducing acceleration and jerk by 3X. Most marlin printers let you change these values in the menu system.
Or you can mark the stepper shaft and pulley and I suspect you will see that it slipped. There are many possibilities though - too much friction is another - the X axis when under high acceleration just can't fight the friction and momentum all at the same time. "belts too tight" can do it also as that can cause lots of friction. Things rubbing that shouldn't. stepper driver overheating (automatically these stepper drivers switch off for a fraction of a second if they get too hot).
You could also try printing something old that is from before you installed the plugin.
I’ll give it a go and see what I come up with. 🙂

If only one of X or Y axis shifts it's 90% of the time caused by the printer itself. Your printer may have worked for a while but something wasn't quite enough. It's almost always a pulley set screw. Does your printer have belts and pulleys that move the X axis? Check them all. Most especially check the one on the stepper. Tighten the hell out of those set screws. If you don't believe me mark the shaft and pulley of all the pulleys.
Also make sure the belts aren't so loose that they can skip a tooth.
