Dasboard look broken

If you re-check that option, is it fixed?

yeah, my goal to uncheck that option without break wordpress

Try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), and delete then replace your copies of everything on the server 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.

If you’d like to manually make a backup of your site first, please follow the steps at https://www.ads-software.com/support/article/wordpress-backups/

Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

The File Integrity checks all the core files with the?checksums?provided by the WordPress API to see if they are intact. If there are changes you will be able to make a Diff between the files hosted on www.ads-software.com and your installation to see what has been changed.
All files passed the check. Everything seems to be ok!

so what does it mean? can you explain more detail?
all core wordpress looks ok
