Can't launch installer on MacOs Monterey 12.4

I previously installed a mod for Higurashi ep1, a little more than a year ago and now that I want to install the voice patch for Umineko Answer this appears when I start the installer. What should I do? Thank you for your help

The issue shows an installer script failing due to missing Python and xcrun. Look at the install.command script to see its dependencies. Check if the script assumes Python 2 is installed and if it handles missing developer tools. The fix likely involves updating the script to check for dependencies or providing clearer installation instructions.
