Comment (by netweb):

 I've just happened upon this ticket now whilst investigating an issue
 upgrading a client to 5.3.x:

 It's also been reported in this support topic:
 > https://wordpress.org/support/topic/error-media-library-icon-picker-
 after-5-3/

 I've still got some more investigation to look into the root cause, and
 any compat in the `wp-icon-picker` plugin
