Windows 10: caps lock, tab and left shift key don't work! windows 10 and 11

before i start, please forgive the non usage of caps writing this, but as the title says i'm struggling with my keyboard.i'm on a legion 5 laptop, on windows 10, and i was in the middle on a teams meet, sharing screen while running an unreal engine simulation when this happened. i dont know if i touched something or if the laptop overheated right there and caused malfunction. here's what i tried so far : - tried updating and uninstalling keyboard drivers- opened the keys and cleaned them from inside, tho i don't think it's a hardware issue.- keyboard troubleshoot- turned sticky keys on and off

Left shift key, caps lock, and tab key not working after updating computer to windows 10.

Basically in what the subject says, those keys have just stopped working after updating to windows 10. My shift on the other side of the keyboard still works but that doesn't help much when the left side doesn't work, nor does my caps lock or tab key work.
