When I press "a" on my keyboard, instead of "a" I got " at", I press window and it opened magnifier and zoom in instead of the window taskbar and when I press "m" it tabs out of the app I'm using,

I sometimes got this issue, I tried to run keyboard troubleshooter but can't find any problems.

I searched google but I can't find any solutions.

Hello,

This is usually a hardware issue with the keyboard. Underneath the keyboard, there is a circuit board with numerous signal tracks. Cracks in the tracks, dust or debris buildup, or corrosion can disrupt the signal flow.

To diagnose a keyboard problem, it's essential to test with the onscreen keyboard or a different keyboard via USB or Bluetooth. If the alternative keyboard works, it's certain that the issue is hardware-related.
