No longer can add media in a listing or article after upgrade

I just upgraded WordPress to version 6 and can no longer upload images via the add media button. Nothing happens. The url is now: https://www.makemoneygal.com/wp-admin/post-new.php?post_type=page# when you hover over the add media button.

I’ve deactivated, reset and reactivated my plugins, cleared browser, pretty much everything.

The only thing that worked was when I switched to a different theme,..I think wordpress 2012. Everything worked fine. Is anyone else having this issue and no of a fix.
