useUtils changes at every render and causes useEffect to be called continuously

e.g.

const utils = trpc.useUtils();
useEffect(() => () => utils.user.example.invalidate(), [utils]);

const utils = trpc.useUtils();
useEffect(() => () => utils.user.example.invalidate(), [utils]);

I'm not sure if it's documented somewhere, I might have read through the code trying to answer this, but I think your dependency should be the result of useUtils only. The result of useUtils is a Proxy object and the useUtils property is specially handled to memoize the context result. Accessing other properties on the proxy creates a new reference every time you access the property.

TypeError: Cannot read properties of null (reading '_def')

Empty router works fine, admittedly null was not a good original choice (my fault).
