This was first time in Shotcut. I have used it many years.

Strange. Try to completely cancel the installation. Reinstall it again, making sure to choose the options that match your computer’s features.

Your desktop environment and its file manager changed and now prevents you from using the desktop file to launch the portable archive. This is not due to any change in Shotcut. Instead, you need to try to run the Shotcut.app/shotcut launch script either from the desktop environment or the command line.
