Midi File Player Won't Automatically Stop - Crashes Macbook Air

I have midi file player playing a very short sequence for 2 measures. I trigger it from a button on my controller. I have the “Stop” field set to “3:1”, and it won’t let me pick any other value. If I run the sequence, it runs fine, but if I don’t manually press the button I used to start the sequence, audio will stop, and I need to reboot my M1 Macbook Air to get any audio again. The standard Mac pinwheel will just stay on the screen indefinitely. Happens every time in the same location if I don’t manually stop the sequence.

Any ideas?

Please upload the midi file

Or you can upload a small gig file showcasing the issue.
