How to ground plug while charging, affects touchpad SEVERELY

Whenever I have my laptop plugged in (ThinkPad X13 Gen 2), the touchpad is extremely delayed, by about a half second, making it almost unusable. I learned that it is because of some grounding issue, but to be honest I have no idea how to solve it. The plug is a USB-C, and it only has slow issues when I plug it in with the original charger. What are some solutions to this?
