wordpress page edit crushed

When I click on edit the page in WordPress pages list I see this appearance https://snipboard.io/6PSWv4.jpg
[ redundant link removed ] This is the page that doesn’t work when you log in of course.

You can first register quickly in my website then login in the same page with popup.

I disabled all plugins, and I used one of the default (Twenty*) theme.
then I enabled them one by one to identify the source of my troubles.
after this, I found out that the problem was in the Yoast SEO plugin.
