Please reopen if you still have this issue with the latest version v10.5

Looks like a conflict with another addon. Whatever addon ...ceAdiBags is might have an outdated AceAddon version. Could you post a list of the addons you use or try disabling that one?

I'll try disabling, my list is long lol

well disabling didn't take care of it...
I went on a different character and disabled all but OmniBar and ACP (Addon Control Panel), and Buggrabber and Bugsack....

These are the errors I am getting...

Anything related to Atlas has been disabled from the login screen, and I even disabled ACP, so there wouldn't be any possibility of preloaded info...
