Gutenberg Compatibilty

I made a page with kingcomposer with Vast theme and it has performed well. (https://prnt.sc/ss0iym)
but when I update to wordpress 5.4.1 (latest) the page is not displayed properly. And this also happened when I used the TwentyTwenty theme. (https://prnt.sc/ss0jkh)
How do I fix this?
