Wow. I actually just saw [a video from Sabine Hossenfelder](https://www.youtube.com/watch?v=ytyjgIyegDI https://www.youtube.com/watch?v=ytyjgIyegDI) about exactly this. Long story short, we don't know if quantum nonlocality is real.
Bell's Theoreom doesn't prove nonlocality. It proves that locality is impossible with statistical independence, that is, the measurement itself affects the quantum system. We can preserve locality if we also accept superdeterminism, which Sabine succinctly puts as, "what the quantum particle does depends on what measurement will take place." We can accept nonlocality and statistical independence or locality and dependence. The former is taken for granted by Bell and many (most?) physicists today but only because the latter "feels" more spooky to a quantum physicist.
The video does the subject justice much better than I can, but the point is that it's not cut and dry!
