3D works fine for me.  Your input file

  10_19_velocity_temp_BCs_temp_ICs.json

works fine.  thermal.json does not work because not all of the
necessary 3D boundary conditions are set.  If extension3D.json is
crashing for you, then there is almost certainly something wrong with
your installation.  Can you send

  config.log
  config.cfg
