PvZ Garden Warfare 1: Primary Weapon Won't Stop Firing (PC)

Recently, I've been having this issue where when I try to play Garden Warfare 1 on PC, my primary weapon won't stop firing despite the fact that I'm not holding down the button in anyway. I've tried restarting my PC, repairing the game files, and resetting the in-game controls. I'm unsure of what to do. Does it have to do with my mouse? Could it be because of some apps I have open? What even causes this issue to begin with? I've tried looking it up too and found zero results.
