Duplicate characters when typing in VS 2022 .cs page

Question

In .cs or .vb code area whenever i type something it gets double.

example a will be aa if will be iiff

Even if I type enter it will add two lines instead of one and backspace and other keys are working in same manner.

When I am typing in .aspx page or anywhere else my keyboard works fine.

I tried few things to solve this like:

1. code clean up, build, rebuild
2. restart visual studio and pc

But still facing the same.
