I got few critical errors regarding the last updates of the skin helper addons (Widgets, Backgrounds...)

Please take a look on these logs:

I can't provide support for those logs as there are banned addons in there.
Remove them before you ask support here. here is a very strict policy about that.

As for the issue, I suspect that you need to restart Kodi

I know, but I don't have any other way to show you.
And I already restart kodi.

I have previous backup, I will try to update these addons again.

EDIT: The same problem right after the updating, getting Error on each of them:
Skin helper service / Skin helper service widgets / Skin helper service background
