Having the same issues here, using Next.js along with next-sanity.

This is still broken as of v3.0.0-v3-studio.1.

The latest version also drops support for drag-and-drop image uploads.

EDIT: @uiw/readt-markdown-editor also does not support writing MDX.

Just hopping in here to also state that I just saw this error /w NextJS 13 and the latest version of the plugin (3.0.0-v3-studio.7). I have the studio setup inside of NextJS as a page route - identical to how it is done here: https://github.com/sanity-io/nextjs-blog-cms-sanity-v3

After doing some more digging this is somewhat of a known issue when combining the markdown editor and NextJS: uiwjs/react-md-editor#52 (comment)

[fabianlee1211]

I hacked around it by duplicating the plugin setup to my Next.js app. Similar to what the Sanity blog template did.

Then move the CSS import to your _app.js and remove the one in the plugin. If you run into any underlying libraries using any browser APIs like react-simplemde-editor which depends on codemirror uses navigator, simply turn the component to a dynamic client side import with Next.

const SimpleMdeReact = dynamic(() => import('react-simplemde-editor'), {
  ssr: false,
  loading: () => <Spinner />,
});
