So, really the problem was about Einstein saying that if Bohr is right then there is information moving faster than the speed of light. Einstein wasn’t saying that he didn’t believe it, but rather if true, then it violated the speed of light in a vacuum. Bohr seemed to actually not understand what Einstein was trying to say, so he interpreted it as Einstein trying to tell him he was wrong.

I think you’re right that Einstein’s instincts wanted QM to be wrong, but he couldn’t argue with the math and experimental results.
