Answer by vengy for Windows 11 Snipping Tool: "This app can't open" error message

I found this workaround at techcommunity.microsoft.com:

1. Open Settings app.
2. Navigate to Time & Language.
3. If the ‘Set time automatically option is switched on”, turn it off.
4. Select “Change” next to ‘Set date and time manually’.
5. Change the Date to October 31 or before.
6. Start the snipping tool.
7. After success, change it back to the latest date.
