Chemical reactions do not occur

Hello, engineer!
I wrote a case study where KNO3 was first thermally decomposed, but after trial operation, the chemical reaction did not occur.
Therefore, I am seeking help
BPN.zip (28.5 MB)

This case is diverging (DT<DT_MIN) at the first time step (1e-6 s) so you have other problems with your case besides the reactions.

There is no divergence when running on a Linux system, only no chemical reactions occur

That is peculiar. I ran on Linux and observed a divergence, and my colleague Hang Zhou observed the same thing.

What simulation time did you reach, and how much real time did it take?

Instead of zipping up the project directory from the command line, can you please go to the file menu and select “Submit bug report”? This includes additional version and debugging information.

Thanks.
