editor error when auto update

Try downloading WordPress again and delete then replace your copies of everything except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

if i upload file manualy work but after auto-update broke again

If you follow what I wrote above, you would be uploading the WordPress 4.0.1 files, that’s the latest version, there is nothing to auto-update to beyond that.

Can you set this in your wp-config:

define('SCRIPT_DEBUG', true);

I’m marking this resolved as there’s been no update.
