Don’t loading forms in page

Hello,
I have a little problem with form, which I paste to popup. Form sometimes doesn’t load. I use divi builder.
Console writes: “Uncaught (in promise) TypeError: Cannot read properties of null (reading ‘language’)”, but i know that property language is not null, just doesn’t load
I thought it was caused by multiple forms on one page, but it happens even when I add only one.
Has anyone experienced this before?
thanks
