very nice addon, especially the Cryptomatte selection and the compatibility with the Super Image Denoiser I like very much.
Unfortunately the addon does not work with Blender 3.0 (yes I know, still alpha).
Hope an sooner update for Blender 3.0.
Let me know if everything is working fine so I can post the version on Gumroad.
For installation, it’s better if you uninstall the old version and relaunch blender to install the new one.
