Hi,
It sounds like you might have encountered an issue with Windows updates or some conflict between the Open Shell and Lightshot software and the system settings. Here are a few things you can try to resolve the issue:
1. Check if your keyboard is working properly by testing it with other applications or try using different keyboard shortcuts for Open Shell and Lightshot.
2. Check if Windows updates have installed any new system settings that might be interfering with the Open Shell and Lightshot software. You can try restoring your system to a previous point before the updates and see if that resolves the issue.
3. Try disabling other keyboard-related software or shortcuts to avoid conflicts with Open Shell and Lightshot.
4. Uninstall...
