Character bug, glitched HUD, and glitched movement?

Yesterday I redownloaded ow after factory resetting my pc to get a fresh start again (it’s something I commonly do). I went into a quick play match and picked ana. I noticed after a while though, my character started slipping around and moving forward and any time I’d aim and stop aiming, the scoped HUD would appear and disappear again. Sometimes if I’d shoot, the sound would play twice and you’d be able to see multiple bullets come out and the bullets left would go to, for example, 18 to 17 to 16 to 17. I have no clue what’s going on. My wifi is fine and my ping is fine too. It only starts to drop when these glitches would happen. Oh and also this doesn’t only just happen with ana. It happened when i was playing on brig and when i was trying out freja. Also I have looked on replays and this isn’t visible in replays… Please help because this is making the game super unplayable and no other forums had the same issue i had.
