Can a Run not terminate for a specific trajectory?

I’m visualizing trajectories of electrons through a silicon material. Before Run 14, each Run completes in less than a second and I can see its trajectory. But if I run one more run, Run 15, in output I get “Run 15 starts” and it never gets terminated.

I’m new and not sure which code snippet will be relevant here.

Geant4 Version: 11.2.0
Operating System: Ubuntu 24.04
Compiler/Version: 13.2.0
CMake Version: 3.28.1

I suspect it is getting stuck. Have a look on the terminal output (not the GUI output). There may be error messages there.

Otherwise, run in a debugger, interrupt in Run 15, and find out what it’s doing.
