What Publish button? Do you mean the Public checkbox under Project Visibility?

No, the entire publication section

When I click on the "publish" button, the entire publishing menu closes

What publication section? What menu?

When I try to upload my project to the Dashboard, I fill out everything and go to the publication menu, click on the "Publish" button, the menu disappears

Good afternoon.So will you help me
