The issue with the MAX8 is that it is fundamentally imbalanced. The larger heavier engines are tacked on to an airframe similar to the existing 737, constantly causing the plane to tip forwards, such that repeated tiny changes are required to maintain level flight. It is these tiny changes that are automated by software and can cause a crash when fed faulty sensor data.

The MAX10 is a significantly longer aircraft. The forwards rotation of the larger heavier engines is better balanced by the forces imparted by the tail acting over a longer lever arm, so the problematic sensor-driven software-controlled tiny changes aren't required.
