Hello @Fafa and welcome to ClassicPress.
The following is based on the assumption that this is the plugin you are using: https://wordpress.org/plugins/advanced-ads/.
I was able to reproduce the error in both ClassicPress and WordPress 4.9 using version 1.23.2 of the plugin. As the developer claims that the plugin is compatible with WP 4.6+, this looks like a simple bug in the software to me.
The error message suggests that the plugin is looking in the wrong place for
plugin.min.js. There is no folder called
wp-includes/js/tinymce/plugins/ and neither should there be.
Someone else reported the same issue on the WP forums (https://wordpress.org/support/topic/failed-to-load-plugin-advads_shortcode/ ). Although the developer says that the issue has been fixed in the latest version, this appears not to be the case.
I think your best course of action is to get back to the developer and report this as a bug.
