Comment (by bobbingwide):

 Having debugged a problem with the File block (
 https://github.com/WordPress/gutenberg/issues/23510 ) I searched and found
 the same issue as reported here.

 My workaround was to use a different prefix for the mime type that some
 Windows browsers see.
 I added the following line in wp_get_mime_types()

 {{{
 'xzip'                           => 'application/x-zip-compressed',`
 }}}

 This resolved the problem for the File block.
 The change does not seems to affect media upload.
