Same issue here. Does it happen if you don't sprint or crouch and just run around? I'm trying to pin down whether or not it comes from multiple key presses at the same time, or maybe the modifier keys like shift or ctrl. From what I can tell, if I press one key at a time, it happens much less, but I'm not sure if it's 100% of the time.
I found a solution to my issue. When I started the game, my computer would constantly Connect and disconnect from a random bluetooth input device. I removed all bluetooth device connections from Windows and now it’s fine.
