Comment (by jblifestyles):

 If someone is looking to address this issue temporarily while waiting on
 the patch to get integrated, and happen to sit on a server, like Flywheel,
 that doesn't let you edit wp-includes....  You can simply add this to your
 theme's functions.php file

 add_filter ('sanitize_file_name', 'remove_percents_filter', 10 );
 function remove_percents_filter( $filename ) {
     $filename = str_replace( '%', '', $filename );
     return $filename;
