Right click not working while holding shift or alt keys

Hello,

I have a Lenovo IdeaPad Flex 5 laptop running Windows 11 Home, version 10.0.22000 Build 22000. I've had an issue for the past week or so where holding down either shift key, or either alt key, mean that my right clicks don't register. This occurs when I'm using my laptop's integrated keyboard as well as an external USB keyboard. It also affects both my laptop touchpad and my USB mouse. I've attempted to change the touchpad sensitivity and remove the touchpad delay, but neither of these resolved the issue.

I was wondering if anybody else has experienced this issue or has an idea for a fix?

Thanks,
Jackson

Welcome to the forum.
First run the keyboard troubleshooter settings>system>troubleshoot>other troubleshooters>keyboard click run
See if this article from Lenovo is of any help.

Thanks for the welcome. I've tried the fixes in the article, and run the keyboard troubleshooter as well to no effect.

And you scanned that there were no outstanding driver or bios updates in Lenovo's automatic scan?

See if the keyboard functions correctly in safe boot. Start your PC in safe mode in Windows

Then try a clean boot. A Windows clean boot disables third-party add-ons that normally load at startup. Perform a Clean Boot in Windows 11 to Troubleshoot Software Conflicts Tutorial
