Random weapon pickup in CE

Ever since the last update, whenever I play CE walking over a weapon on the floor has the random chance to have me swap my active weapon for it and then despite having the prompt, it taking multiple key presses over several seconds to pick the dropped weapon back up. This hasn’t happened to at all in Halo 3, Reach, or any other games on my pc, only CE.

Also this shouldn’t be linked to the unable to pick up weapon bug in CE since I already have the windows 10 update they said fixed that.

I am experiencing the same bug to, very annoying.

Edit: I want to add that it seems to happen when throwing a grenade, I play on pc btw.
