Website migration – please help

Hi, I recently migrated a website to a new host, but one of my wordpress installs doesn’t seem to work. I double checked the files migrated and double checked the database installs, but I get this error message when I try to load anything on the site.

Required file ../adsense-now-frontend.php not found in __DIR__/admin.
Please reinstall the plugin.

The domain is checkenginetroublecode.com

How do I uninstall or reinstall the plugin without having dashboard access??
