_Geant4 Version: geant4-v11.1.1
_Operating System: Ubuntu 22.04
_Compiler/Version: GCC 11.4.0
_CMake Version: 3.22.1

It looks like the fundamental issue is in DetectorConstruction::StoreParTree but you’ll have to run the application through a debugger like gdb to pinpoint the cause.

I tried to make the executable by direct compilation but It did not work. This code was running well in an old version of Geant4, but I am not able to run it in a new version.

It’s impossible to tell from that information what the cause could be - the only way to determine that is to run in a debugger to pinpoint the line/state in the code and program.
