Finding the root of the graph... The probe is outside of the medium!!! Segmentation fault (core dumped)

[zhouxinyue-97]

When I ran the program, I found that the program stopped after only one simulation, but in the input_opt.json file I have set "number_of_runs" to 2. In addition to the expected output of a simulation, the report result also has a title Output, check the cpu and GPU and find that there is no memory overflow. I hope to get some suggestions for checking the cause of the error.
