Your code corrupts incoming MOSI messages somehow. I can see this on a digital logic analyser, sending data between teensies. Neither slave nor master is getting data.
It seems like two forks are fixing major issues with your code, but without any commenting or documentation in your code I cannot tell what's going on. PJRC directly links your Repo on his website, so it would be great if you could fix this for the community :)

If you are using a T4 as a master, you need to use common ground between master/slave near the 5V pin, NOT next to pin 0

if you are using other teensies as master, it should work fine

SPU_MSTransfer_T4 solves this issue and offers additional features
