Home Front Page not loading

I couldn’t open the home front page with “edit with TagDiv Composer” it keep on loading and showing this error. No idea what it is.

Error at zones: 6(models) : 0(dom). The model does not match the content Current state has involved an issue. You could try an UNDO operation (CTRL+Z / CTRL+SHIFT+Z)

Hi,
Starting this year, we have the same problem to edit individual pages using TagDiv Composer. The panel on the left loads, but the page to edit doesn’t anymore. There’s a loading screen and then an error appears, as in the attached screenshot. I have tried all the advice from the forum, unfortunately to no avail. If I keep refreshing the edit page, on average 2-3x a day the edit page loads and works. But usually (99% of times) it doesn’t and it’s like the attached screenshot.
All settings and requirements of Newspapper are met, there are no errors, nothing is missing, limits are increased, plugins are up to date. I tried desactivating all plugins and leaving only tagDiv ones, I also reinstalled tagDiv Cloud and Composer, I cleared cache many times. It does not help.

Please advise, because currently it is impossible to run the site without the ability to edit the pages and our business is at risk because of that.

Here’s the htaccess:

</IfModule>
