 == Update

 /class-wp-filesystem-direct.php#L545 This] is where it fails.

 The error is:
 PHP Warning:  mkdir(): No such file or directory in  <path>wp-
 admin\includes\class-wp-filesystem-direct.php on line 545
 PHP Stack trace:
 PHP   1. {main}()  <path>wp-admin\admin-ajax.php:0

 PHP  10. mkdir()  <path>wp-admin\includes\class-wp-filesystem-

 The path being sent is:


 I've tried:

 - adding a trailing slash (this is specifically removed earlier in the
 above method, so it was a test of curiosity.
 - converting the slashes to `<root>\wp-content\plugins\hello-dolly` in
 line with Windows filesystems.

 The error still occurs.

 I then tried this:

 mkdir( $path, FS_CHMOD_DIR, true )

 The first two arguments don't make the difference. The third argument
 enables recursive creation of directories. This works, but it also deletes
 everything else that's in the `wp-content/plugins` directory.

 Investigation ongoing.
