Authoring CQ.flow and CQ.workflow.flow.Step undefined after 6.5.12 upgrade

[tim_funk]

It seems I have a similar issue to https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/error-while-opening-page-e...

For me, this appears to have happened between the 6.5.11 and 6.5.12 upgrade. I did a quick check if I had conflicting overlays in /apps but nothing stood out. I tried rebuilding libs (to no luck).

I see the following errors in the JS console:

As well as a "core.min.js:formatted:10717 Handler of component is invalid -> TypeError: Cannot read properties of undefined (reading 'Step')"

I suspect I might have an overlay of permission issue somewhere as a simple tweak.

Possible solution:

Clear localStorage

After walking back the traces - I saw references to localStorage and on a whim decided clear (most of it - I left a few entries related to my custom site)

After which  - I didn't see the issue.

I then tried to edit in Incognito mode as a double check / verification - and the same error was no longer there.

This might be worth adding to release notes.
