Comment (by vanyukov):

 Another observation - the upload process is really long. It's taking
 anywhere from 2 to 5 minutes on a test site. With WordPress 5.2.4 it was
 30-40 seconds.

 On a VVV install after 38+- seconds I get this UI notice: {{{Post-
 processing of the image failed. If this is a photo or a large image,
 please scale it down to 2500 pixels and upload it again.}}}, {{{async-
 upload.php}}} fails with a {{{502 Bad Gateway}}} and
 {{{WebKitFormBoundary}}} error.
