My WT is completely bugged out

So to start, every time i have to reverse or move up i have to press SHIFT key for some reason? But shift key is only binded to sniper mode and nothing else.
I cant look around using C because it immedietly snaps back
I also need to press SHIFT before i press repair (F) for some odd reason because it keeps reseting into oblivion.
I tried reseting settings, then i tried reseting game, then i tried reseting entire PC but nothing worked.Here is a Youtube video
