If you’re on SiteGround also and know that it’s the 6.2 update causing the issue BUT don’t want to restore, they can roll it back with the core file updated. They’re back logged for good 30-60 minutes I’m assuming due to this 6.2 update causing issues for so many.
Otherwise, yes, you’ll need to restore from the Backup section to the previous save. Just make sure you disable the automatic update in wp-config.php file.
And add:
define( ‘WP_AUTO_UPDATE_CORE’, false );
