Uncaught error ace.edit causes blank edit post screen

One of our users can no longer edit certain posts because of a javascript error. This results in a blank page instead of the editor.

Looking in the browser consule I see the following error:

Uncaught error: ace.edit can’t find div #single_custom_css_ace
at object.t.edit (ace.js?ver=5.3.2.1)
at HTMLDocument.<anonymou> (scripts-ace.js?ver=5.3.2.2)
….

The user can still create new posts and currently encounters this problem only with 2 posts. Other posts can still be edited.
None of the posts that have problems had custom CSS.

Hard refresh, clearing browser cache do not solve the problem.
Problem occurs in both MS Edge as Google Chrome (no other browsers installed)

Other users have no problems editing the same posts.
