Comment:

 @sky_76 I tried logging out `$args['parent']` on that line and it is
 always either a `string` or `false`. Perhaps you have a plugin that
 registers an admin menu node with a `parent` supplied as `null`? Can you
 log out the `$args` to find out what plugin/theme that is?

 In any case, it makes sense to improve the type checking here. I've opened
 https://github.com/WordPress/wordpress-develop/pull/11055 to fix. Please
 test that as well.
