I haven’t been able to fully fix this issue, but I’ve found a workaround.
In order to force the editor to load, you have to enter the Avia code to the page url.

So if editing a page, and it won’t load the editor, I enter this at the end of the page url: &action=edit#avia-tab-2
And hit enter to make it reload the page. This will allow the blue editor button to be clicked, and will load the fancy editor.

I have to do this every single time when editing the page, is to click on tabs 2 or 3, and hit enter to make it reload, otherwise it’s just loading and loading and loading.

Similar issues exist within the other pages, like the Widget page. There I need to add “#available-widgets” to the end and reload the page. Then the widget panels will actually open.

There’s also something funky with how the media panels work, but I haven’t yet figured out how to make it consistently work. So I just open it so many times that it finally opens the “normal view”. The problem with the media tool is that it opens this “bare” HTML view, where each image would need to be opened separately, to see them, and drag&drop uploads aren’t possible.

When I try it enough times, it opens the more standard media viewer with preview thumbnails etc.

But yeah, this sucks, big time.

It takes SOOO much time just editing anything. And it feels silly to keep a text file with the different codes available for pasting in…
