Keyup event error

Whenever we create a new pop-up or try to update an existing, an error appears and the editor box functions disappear.

This is the error which occurs upon saving:

Failed to load plugin: chch_lp_keyup_event from url https://apartmentsthewoodlandstexas.com/wp-includes/js/tinymce/plugins/chch_lp_keyup_event/plugin.min.js

Thank you in advance for your reply.
