MacBook Air Mojave failed to start after extension installation

Operating system:MacBook AIR MOJAVE
Slicer version: SLICER 4.10.1
Expected behavior:starting
Actual behavior:failed to start

The laptop fails to start or Slicer?
Which extension did you install?
Does Slicer start correctly if you disconnect from the network (unplug the network cable and disable wifi)?
Does Slicer start correctly if you remove Slicer settings file?

Thank you very much
