Fatal error: Namespace declaration

Can you navigate to /public_html/wp-includes/sodium_compat/lib/sodium_compat.php Via FTP or cPanel File Manager, and share the first 10 or so lines from that file? It should look like this: https://github.com/WordPress/WordPress/blob/master/wp-includes/sodium_compat/lib/sodium_compat.php

If it doesn’t, and there’s lines above namespace Sodium; for example, then it’s likely your site has been compromised. If that’s the case, carefully follow this guide. When you’re done, you may want to implement some (if not all) of the recommended security measures and start backing up your site.

ERR_FILE_NOT_FOUND is a browser error. As I said in my response you need to find the file via FTP or the File Manager in your hosting control panel, not visit it in your browser. If you don’t know how to do that you should contact your host. Point them to this thread, it will help them understand what you’re trying to do.
