I believe Bell proved there is no hidden variable theory that matches quantum predictions.

As I understand it, that's correct, but I'm an old fashion type like Durus, who believes we will prevail eventually. Also, Einstein believed that QM was incomplete and there were hidden variables to explain it. His opinion is pretty difficult to simply disregard.
Bell's theorem also seems to prove that any explanation of quantum behavior has to include non local faster than light communication.
