Simple topology optimization problem fails to run on my machine, no error message

I have the following optimization case below, with four fixed supports at one end of the structure and a hole with a downwards force on the other end and design space in red, and as far as I can tell I've followed all the steps in the basic Altair tutorials correctly, but this case does not run on the default optimization settings, and I'm not sure what I'm missing. I've attached the model in question, and was wondering if this could run on anyone else's machine?
