Problem using function fast marching from exchange

I try to use the function fast_marching from the website: https://de.mathworks.com/matlabcentral/fileexchange/24531-accurate-fast-marching

In the beginning it is necessary to generate a mex-file from c-Code. This process is worked after some problems that I could fix. But now there is a new problem and I can't find a way to fix this one.

There is no error message and sometimes there is a matlab bug and the whole programm is crashing. I guess the problem appears in the rk4-function.

The command window shows the following:

Distance Map Constructed

Find Branches Iterations : 0

And than the programm stops working. Maybe someone of you can help me.

Edit:

I use a MacBook Pro (version 2019) and Matlab R2019a

I also tried to run the function on a windows PC over there it worked. The problem is, that I need it on my Mac.

Thank you guys for helping me out!

Best
