Control key appears to remain pressed (stuck) in Battlefield 6.

The weirdest thing is happening in Battlefield 6. When I am in the game, and I press the left-control key to crouch-hold, I crouch. But when I release the left control key, I remain l crouched. Since it is crouch-hold, I should stand right up upon releasing left-control. Standing up after releasing left-control does not happen. 

 Basically, it's as if my left control key is kept on being pressed by my finger, when in reality I have lifted my left pinky finger off of the key. Is this a bug? Has this ever happened to anyone?

I even made sure the correct key binding keys were being used, which I verfied in key-binding settings for infanty. 

crouch-toggle "c"

crouch-hold "left control"

I believe it is only the control key that is bugging out.

For example, when I keybind crouch-hold to "c", I was able to use "c" as crouch-hold sucessfully. That is to say, I can press and release "c" and I will crouch and stand up accordingly. 

The control key works while in another game, and normally while outside of a game during regualr computer functions e.g. copy and paste. The problem was encountered even while using separate keyboard.  

I am enjoying this game a lot right now and believe I will enjoy it for years to come! But, it will be difficult to play effectively as crouching and standing up smoothly is important to success in the game. 

Thank you for reading and please help!
