so i am trying to edit my widgets under the appearance tab. and all of the sudden they are gone .... the only option i have is "manage with live preview" ... which i click .. then i get an error .. and i think its pointing to wp views ... see the images below ..
The issue is being caused by the latest version of Elementor, however the workaround in the erratas page above should be able to get this working for you again.
Are you able to provide me with a copy of the site so that I can see exactly what is happening here? As we have customers with the same issue reporting that the patch resolves their issue.
