What happened?

The problem comes from the file modules/launch_utills.py: 307

After investigation, it was found that when the Package parameter was ‘spandrel’. So it caused abnormalities

The following is the modified code, adding a judgment that returns False if version_installed is empty

Steps to reproduce the problem

Version updated to 1.9.0
