Add-on Installed But Fails To Launch in Kodi 20.0

[UbuntuMetal]

I've successfully used Skin Helper Service ColorPicker on 2 Android TV boxes, one running Kodi 18.1 and the other Kodi 19.3, but on a 3rd one with the latest Kodi 20.0 it installs fine, but when going to pick a custom colour (in Aeon Nox Silvo skin), it simply comes up with Skin Helper Service ColorPicker Error. I've tried to Install from zip using the latest download, and it tells me it was updated, but no change in behaviour. I've even manually replaced all the files, but it just prompted me to install the add-on again, and once again I can't use it. I've had a look online for a potential answer, but all I've seen is people mention it doesn't work with Kodi 20.0.

I've attached the log file, which mentions script.skin.helper.colorpicker numerous times, so if there is something I can manually edit in default.py or something, I'd happily do that to get this working. Also, I went to see if I could update it, but it isn't listed in the installed add-ons section, though it's definitely installed. Many thanks in advance.

Not a fix but a workaround:

1. Download https://github.com/kodi-community-addons/script.skin.helper.colorpicker/archive/refs/heads/master.zip
2. Place the file somewhere where Kodi can access it
3. Go to Kodi's menu to install "addons from zip" (https://kodi.wiki/view/Add-on_manager#How_to_install_from_a_ZIP_file)
4. Choose the downloaded file
5. It should say "Addon Updated"
