For the past several days, I've been trying to use Workbench 2024 R1 to conduct a parametric study involving the EDC model with Stiff Chemistry and ISAT enabled in a 2D axisymmetric domain. Unfortunately, I've been hitting a cortex error immediately at the start of every design point calculation in the parametric table. I opened the TRN file to see what the problem is, and here are a few screenshots of what it shows:

I made sure that the physics and solver setup are good by running the first design point in Fluent manually, so I know that shouldn't be the problem. This error only occurs in the Workbench parametric sweep and also in the native Fluent parametric study tool. I will say that the TUI string: "define models species clear-isat-table" was intended to trigger alongside the initialization TUI string, with both being in the same Pre-Initialization block under Calculation Activities, but it appears it failed to do so. I'll have to see how to fix that later. I tried manually clearing the ISAT table in the Integration Parameters window in the Species tab, but I don't believe there was anything to clear to begin with, so nothing happened. A fix to this issue would be greatly appreciated.

If it helps, on the desktop I am using I've set the simulations to run on 22 out of 24 cores. The CPU memory is 64 GB, and I've set the ISAT table storage limit to 32 GB. Lowering the both CPU core usage and the ISAT storage did not fix my problem.
