in node_modules/typedoc/dist/lib/output/renderer.js.

This fixed it for me: if (!type || !type.qualifiedName || !type.package) { but not sure if it won't cause other problems.

{
    ...,
    "typedoc": "^0.22.8",
    "typedoc-plugin-markdown": "^3.11.11",
    "typescript": "^4.4.4"
}

Downgrade the version of typedoc to 0.22.10 is okay for me.
