I am facing exactly the same issue (1.0.8). I have however some extra notes I can mention :
If I keep the path to : /modules/contrib/ckeditor5_template/template/ckeditor5_template.json.example, CKEditor is appearing just fine. The issue only arise when I define another path.
However, the path I define manually is correct because when navigating with user 1, I have no issue. This only happen with account with less permissions.

Same for me. After re-arranging the order, it seems the status of thetext format "webform_default" was set to false (for a reason I don't know). I've just reset the status to "true" and imported the config and that seems to do the trick.
