Cms WordPress errors

Hi, initially my website had wordpress 4.3 and I did a manual update to 5.7
Since then it doesn’t work to post anything from cms, in fact the editor doesn’t appear, it doesn’t work to add pictures receiving an error “try later” and that’s about it ..
What do you think is the problem?
The site is still ok but I have these two problems
P.s theme is avada but I don’t think it affects the cms ul
