How to solve this messy display (loading) issue

Hello,

I’m running a landing page wih Divi theme which looks like this (link), but it happens regularly that it does not display correctly (it displays some basic HTML version with white background, basic forms and design messed up), until I log into wordpress and update the page on divi builders side, like it’s stuck in the first milisecond load.
This causes me to lose conversions.
I get it’s probably related to the loading speed, but I have the litespeed cache plugin, and no issues are shown on paper on my host’s side.
Every time I log in and just click on “update page” with no changes, it goes back to normal for the rest of the day. But I always need to check my page cause it happens repeatedly (daily)
(Don’t know how to add a screenshot).
