Hi
I don’t know what version you upgraded from. We have tested with WordPress 5.7, it works fine.
Please try to fix:
– update BM Content Builder plugin also, the latest version should be 3.7.1.1
– stop all 3rd plugins to test
– purge cache, I found the JS files are minified.

If it doesn’t work, may I check your website? Could you please send your question(this topic URL) and wp-admin(URL / username/password) to seatheme.net@gmail.com ?
(If there is the Jetpack plugin, please disable “Allow users to log in to this site using WordPress.com accounts”)
