Solver stalled with Spalart-Allmaras model

I have a 1-stage compressor model consisting of a rotor and stator. I have already analyzed it with the SST turbulence model. The y+ for both domains is about ~1. I was trying to test the Spalart-Allmaras model which is still a beta feature in CFX. But when it started in the solver, the solver just stopped and did not move forward from "Initial Conditions Supplied by Fields in the Input Files". Even when I clicked the stop button to kill it, it did not respond.
I tested with default and scalable wall function, but nothing changed. The version of Ansys is 2021 R2. Below is where it stopped: Code:
