ctrl+shift not working together


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.
Does anyone can solve this problem?
Does Winkey + Space works?

For me specifically, left ctrl and shift not working together only seems to only happen if I plug my keyboard in the "keyboard" usb port of my kvm. Plugging my keyboard in one of the "generic" usb ports of the kvm (or directly in the computer usb ports) works fine.


I had the same problem but I was able to fix this by turning off shortcuts in AMD driver software.

@Souvik17 For me the problem only happens due to KVM, since it uses the Left Shift and Ctrl keys for switching between computers. What works for me, instead, is using the Right Ctrl + the Left Shift + whatever key completes the default shortcut I'm trying to use.

I appreciate that tip (windows key + space bar) as my accents have been stuck on and I need an international keyboard. 



Please note that I have found a fix for this issue and feel that this thread should be updated. So as to not have people continue to be misled. Please review this web link to Microsoft Teams Support Page - Review the Keyboard Shortcuts and note that the key combo for CTRL + SHIFT + Spacebar has been remapped in the latest version of Microsoft Teams - { https://support.microsoft.com/en-us/office/keyboard-shortcuts-for-microsoft-teams-2e8e2a70-e8d8-4a19... } That an End User needs to Turn OFF their Microsoft Teams inside of the Application's settings or locate the running Process in the Windows Device Manager. I hope that this will be helpful for people in the future. -Brian
