Got the same issue today after upgrading a bunch of codemirror related packages.

 "@uiw/codemirror-extensions-langs": "^4.21.21",
 "@uiw/codemirror-theme-github": "^4.21.21",
 "@uiw/codemirror-themes": "^4.21.21",
 "@uiw/react-codemirror": "^4.21.21",

Manually deleted node_modules and pnpm-lock.yaml, ran pnpm install once more and it worked again.
