@khanhnguyen2810 it’s likely that you have unloaded a file that is needed on the homepage, instead of one that is not needed. It would be useful if you can check this post for a way to determine (as close to 100% accuracy as possible) if a CSS file is needed on a page: https://www.assetcleanup.com/docs/how-to-check-if-gutenberg-blocks-css-file-is-needed-or-not/
The original page should restore without any problems whenever you reset everything in “Tools” from the plugin’s menu. Note that the original CSS/JS files from plugins/themes or external locations (e.g. a CDN) are never altered or removed by Asset CleanUp. The plugin just unloads them depending on the rules on that particular page. You do not have to reset everything to restore the original page. Just load the file back (remove the unload rule that you placed in the first place), clear your browser’s cache and any page caching (e.g. if you’re using a plugin such as WP Rocket or you have a page caching service from your hosting company), and everything should be 100% as it used to be.
