Can't use visual editor in article

When I try to insert new article or edit another already published I can’t use visual editor, it is like corrupted, if i write something they don’t appear but hmtl editor registers the input. Yesterday it works fine. Today I’m tring to write new article but it is impossible! I realized too that there are some errors when try to modify my theme from its panel but I cleared browser cache and problem is solved. I tried to update wordpress, restore backup, database and file (Yesterday I installed backWPup plugin to automatize backup), return to default theme, disable all plugin, changed browser but nothing tinymce doesn’t work…there is an image with my problem: https://emanueldinardo.com/wp/tinymceproblem.png
