Specs are fine. But it seems that some software or driver might conflict with the Unity engine.

Do you use keyboard or controller. Try to switch to see if the behaviour is still there, if not, focus on your input device (driver or related inout device software you installed for it).

Try to unload any software not necessary, also temporarily deactivate AVP for a brief test if things changes. Try to go offline in Steam or do a clean Windows bootup. Try to narrow the culprit down.

So, it's not about the game, more like a overall pc problem.
I would check things you said, thanks.
