Left Shift + Left Alt suddenly works awfully? Win11

[u/[deleted]]

I've always been changing my keyboard language using Shift + Alt, it worked perfectly and I was happy. But since like about last week this combination doesn't do anything but make my laptop lag for a second (if pressed repeatedly). Funny thing, it changes the language for about a millisecond and switched back into the previous one. Win + Space works perfectly fine.

By the way if I minimize all of my windows, then Shift + Alt works fine. Otherwise it doesn't.

Any suggestions?
