Error Occurs During Add-On Installation in Blender 3.5

[kazuoay]

Hello to the cats-blender-plugin development team.

I am a user of Blender 3.5 and have encountered an issue with installing add-ons. Whenever I try to install an add-on, an error occurs and it cannot be installed successfully.

Could you please advise if there is a solution to this problem? Thank you very much.
