Export from step to glb

Hi , so i'm trying to export from step to glb .
The file name is TLStpManager.cpp.
But it crashed due to an error in Annex line 46(TLStpManager.cpp), Using OpenCASCADE 7.6.0.
I don't know how to use " Prs3d::GetDeflection(aCompound, aDrawer)" to setting Deflection.

"anAlgo.Perform(aCompound)" is crashed.

I don't know how to solve it.
