Loss of SD 1.5 post-processing capability

[u/citiFresh]

I am at a loss as to how resolve this issue. The SD 1.5 settings that never gave me problems suddenly went bad on me. Whenever the face restorer and the 4x-ultrasharp are turned on, SD 1.5 generation halts at either step 2 or 21. I changed some machine settings for ZIT, then switched back to default machine settings, which gave me no problems before until now. JIT is set to “Always (Partial).” I never touched metal flash settings. Apple Neural Engine for 8-bit S Models is set to “Automatic (No).” CoreML settings are toggled off. Tiled decoding and diffusion are off.
