The options I can think of right now are to try to verify the file path by making sure the file path you're using is correct and points to the exact location of the application. Check the permissions by ensuring that you have the necessary permissions to execute the application. You might need to use the "chmod" command to make the application executable if necessary. Make sure that the application file isn't corrupted. You could also re-downloading the application and see if the issue persists. You can also check the system logs for more detailed error information. Instead of using the "open" command, you can also try launching the application directly using its full path in the terminal. But if that doesn't work idk
