WordPress 5.5 upgrade breaks administration panel javascript

[jadeconcept]

In product edit area, clicking on tabs doesn't open the tab any more on WordPress 5.5, the new update released. It appears that this is due to javascript errors introduced by WP eliminating wpColorPickerL10n.
This broke a number of plugins. Easy Cart folks, please release the fix as soon as possible!

Anyone has a solution in the meantime?
