Ok this is because the camera has a parent but you are not restoring the parent of the serialized camera

The address is for a local project(http://localhost:1338/#M9VRYX#1).
I need an online address.

If you change http://localhost:1338/ to https://playground.babylonjs.com/ you will get the online address https://playground.babylonjs.com/#M9VRYX#1

The viewpoints of step2 and step3 are different, you need to look at them again.

Added an alert before switching cameras to see the perspective change in comparison
Added an alert at line 57 in step 2 and at line 68 in step 3.
You can see the change in perspective by comparing
