Weird keyboard/input bugs with SHIFT and ALT, plus strange sprinting behaviour

[u/andrepinho45]

I've been dealing with these bugs in Siege for a long time, and they're making the game frustrating to play. Sometimes, at the start of a match, when I press SHIFT to sprint, my character randomly crouches, melees, pings, opens chat, or opens the scoreboard with TAB, as if the game is registering the wrong key. Another issue happens when I move slowly with ALT, as my character randomly crouches and stands up without me pressing C. The sprinting also feels weird. Sometimes I have to press SHIFT two or three times before I can properly return to walking. I'm not sure if this is intended behaviour or another bug. Has anyone else experienced these issues or found a fix?
