ctrl+shift not working together

[Souvik17]

I am running windows 11 21H2 and suddenly I am not able to use the left shift+ctrl together. Tried changing language settings typing methods as well. Some issues I am facing are:

- Unable to inspect element using ctrl+shift+i / open incognito using ctrl+shift+n, etc.

- Unable to select multiple cells or words/use shortcuts in office tools and in Google tools like sheets, docs, etc.

Note: Individual ctrl and shift keys work perfectly fine and the issue is only with the left side ctrl and shifts. Right side ones work fine (even together).

Current windows specs:

@Souvik17 I am facing the same issue, left ctrl and shift are not working together, however, the right ctrl and shift work fine. I am also using Windows 11 home edition.

I am experiencing the same problem as well, I have tried uninstalling and reinstalling the current keyboard driver but that didn't work. I operate a windows 10 pro.@Souvik17

I faced the same issue, but combining left ctrl + right shift worked for me.
