Keyboard Shortcuts Issue
I've encountered a bug where keyboard shortcuts, such as Ctrl+C, Ctrl+V, and Ctrl+Z, are not functioning correctly. This issue is happening consistently.
This is not uncommon :(
Do you have any clipboard managers installed? Any extensions in browsers that can have deal with text?
What options do you have enabled in Preferences > Clipboard Handling?
If you open History panel — do you see the steps you want to undo there?
If you open Edit menu — do you have Paste commands enabled there?
