CATS Blender Addon Not Working

Solution of the establishment of the Cats Blender plug -in problem:

It sounds like you’re having trouble with the CATS Blender plugin. Here are a few steps you can try to resolve the issue:

1. Install the Development Version: Sometimes the latest official release might not be compatible with your Blender version. You can install the development version of the CATS plugin, which might have the latest fixes. Go to Preferences > Add-ons > CATS Blender Plugin > Install Development Version.
2. Check Compatibility: Ensure that your Blender version is compatible with the CATS plugin. If you’re using Blender 3.5 or newer, you might encounter issues. Consider downgrading to Blender 3.0 or 3.2, which are known to work better with the CATS plugin.
3. Manual Fix: If you’re comfortable editing Python scripts, you can manually fix the plugin. Open the __init__.py file in the CATS plugin folder, look for the line containing bpy.context.window_manager.addon_support = {'OFFICIAL', 'COMMUNITY', 'TESTING'}, and remove the 'TESTING' part. Save the file and reinstall the plugin.

Manual Fix Details:

Extract the zip file and open the init.py file, and then only delete the ‘Testing’ string and save it. Save and install the external folder again as zip in Blender preferences.
