It happens when playing Steam games, and it also happens when using Vinegar to play Roblox. When I'm pressing any key from my keyboard, the touchpad basically stops working (except for the right click and left click, they do work). So basically I can't move and look around at the same time.
I have a Lenovo IdeaPad 3 and I'm using xfce. Pls tell me if u need more info.

You likely have configured a setting so that the touchpad is disabled on keyboard press, check your xfce touchpad settings, maybe also throw in xinput/xinput list-props of the device in question.
