I applied the patch and tested with all default themes (twenty-*) and two custom themes and it works fine.

Can you please confirm that same thing, issue is gone when changing Template Pack to Legacy, is happening on your side too.

Hello @r-a-y
I am also using fresh WordPress setup, but still facing the issue. Here are the setup environment details:
WordPress: 4.9.7
BuddyPress: 3.1.0
Twenty Seventeen: 1.6

I enabled script debugging by adding following code to wp-config.php:
define( 'SCRIPT_DEBUG', true );

The issue is arriving when I am opening customizer from any page, either I am in Appearance section or Pages.

I tried one setting in BuddyPress and issue gone. I changed Template Pack from BuddyPress Nouveau to BuddyPress Legacy in Admin Panel > Settings > BuddyPress > Options tab > Main Settings > Template Pack.

When changed “Template Pack” to “BuddyPress Legacy” it’s not loading any js containing wp.customize.control, so it’s not generating any error.
