That's not the most extensive thread title we've ever seen, but okay.

what is wrong

Quite simple. Upto Kodi 18, the Python-2 version was used for creating scripts and other tools. Now that Python-2 is "EOL", we moved on with Python-3 as the python interpreter in Kodi 19 and above.
This means that your add-ons will also need to be updated, if not done already automatically. When upgrading Kodi to a higher "major" version (17, 18, 19..), it's best to first go back to the default skin Estuary, to avoid issues with unsupported skins.
