Richeditor & dashboard bug

I’m having two issues with my installation on a website. I’m not quite sure how to explain it, so I’ll describe what’s happening and attach a screenshot. I think there’s probably a connection between the two, even though I can’t quite figure out what it is.

  1. This is a bug in the dashboard and in the RichEditor field. When opening a “create” page in the backend, RichEditor doesn’t load, while everything else does. But when opening, for example, the Media Finder, RichEditor loads automatically.

  2. When opening a list, the backend menus don’t behave as they should. Ex: When clicking on a menu, it’s supposed to display the submenu, but half the time it redirects to the dashboard. When the list is displayed, the rows aren’t clickable to access the update page. But if you click to sort, the list rows become responsive and behave normally.

When I inspect the console, I only see this error:

[Error] Failed to load resource: the server responded with a status of 404 () (modules/backend/vuecomponents/monacoeditor/assets/vendor/min-maps/vs/loader.js.map, line 0)

But a map file normally has no impact.

I noticed this under October v4.1.x, then I updated to v4.1.19, but the issue persists, even though other sites with the same configuration are working fine.

Does anyone have any ideas?
