 I had same bug at 2017-03 in WP 4.7.3 and used fix
 {{{
 define('CONCATENATE_SCRIPTS', false);
 }}}
 without any idea of what happened and what am I doing. It worked, but it
 wasn't a pleasant experience.


 Reinstalling WordPress does not fix it, and it always needs a manual fix I
 thing it is a good thing to report it as a bug

Comment:

 As far as I've seen on the support forums there is a chance that some
 cache somewhere is not updated fast enough which sometimes results in js
 errors on the (old) Edit Post screen. These errors "break" the classic
 editor, even when they are not directly in it. They usually "magically"
 fix themselves after some time when the cache is updated.

 Best place to get help for these cases is the support forum. There are
 several steps to try to fix or determine what's the problem.
