Unable to run `make train_and_show` or `make train`

After errors leading me to learn that XCode is also a dependency for this project, I was finally able to compile the cpp files/actions when running make train_and_show or make train. However, I am running into spine error: TimeoutError: Spine did not process request within 100.0 ms, is it stopped?

EDIT: I was able to get a few seconds passed the error by hardcoding the timeout timeout_ns = 300000000, and it appears to run for a few seconds, detect a fall, and then reach the error again. Also, there are always 6 simulations that start when running train_and_show (even after force quitting all of them) (image attached). Thanks!

For ref: macos 15.1.1, m3
