 * So after I updated to the latest version, whenever i try to use the Customizer
   interface, I get the error “JSON_PARSE_ERROR” right after I click “save changes”
   with no other explanation.
 * What can I do?

   and I still get the same error.

 * Apparently there is a corrupted customize_changeset post in the DB. I presume
   you have an existing draft saved. Not sure how it would have been corrupted, 
   but to start over you should be able to open the publish settings panel (via 
   the gear icon) in the Customizer and hit the link to trash the drafted current
   changes.

 * If you can figure out a way to reproduce the problem that would be ideal so we
   can fix the issue in core.
 * Here’s where that error is returned: [https://github.com/WordPress/wordpress-develop/blob/1c4f57f425fed9bec01e558d22d1fb751881e347/src/wp-includes/class-wp-customize-manager.php#L1120](https://github.com/WordPress/wordpress-develop/blob/1c4f57f425fed9bec01e558d22d1fb751881e347/src/wp-includes/class-wp-customize-manager.php#L1120)
 * Next time it happens, find out what the contents are for the `post_content` of
   the `customize_changeset` post.
