Returning objects with type `unknown` in `beforeLoad`/`loader` started throwing error after v1.132.x

[MTG2000]

Which project does this relate to?

Router

Describe the bug

In earlier versions it was okay to return an object with a type that contains unknown for one of its properties like:

type TypeWithUnknown = {
  value: unknown;
};

export const Route = createFileRoute('/_layout')({
  component: RouteComponent,
  beforeLoad() {
    const obj = { value: {} } as TypeWithUnknown;

    return { obj };
  },
  loader: async ({ context }) => {
    return context.obj.value;
  },
});

But after updating to version 1.132.6, the above code throws this error:

Call signature return types '{ obj: TypeWithUnknown; }' and '{ obj: { value: {}; }; }' are incompatible.
    The types of 'obj.value' are incompatible between these types.
      Type 'unknown' is not assignable to type '{}'.

Steps to Reproduce the Bug or Issue

Go to the _layout file in the code repo above and you should see the errors on beforeLoader and loader

Expected behavior

I believe this is a bug and the behaviour should remain consistent with what it was in earlier versions.
