Error sound when I press command with anything.

[6ftunder]

So, I don't know why this sometimes happens, but when I press command with T or with W or with ANY key, my mac makes that error sound like when a window opens where you can only click on something inside of it but you try to click on something outside, that dull error sound.

I lose my mind every time I open a new tab because I get that sound, and if I were to highlight this text using command+a, it would be there again. Is there a way to turn this off without having to restart it?

Try an external keyboard. If it works then most likely a spaceship crashed into your house and scared the dog who in a fit of confusion bit your cat who then peed on your keyboard. If not then maybe reformat... IDK.
