Plumberscode,
I had the same exact same issue and here’s how I was able to fix it. Go to public_html/wp-includes/default-embeds.php on your server and hide line 33 and any other line that gives an error after that by using
/** hide */
After you that, go back to your wordpress admin login page and it will ask you to upgrade your database. After you upgrade, the hidden function should be fixed
