Editor: Error when loading the json archive with Directional Light

[Stapxs]

Description

PS: I'm not good at English.

I edited some content in editor and saved it, and some errors occurred when loading again. After some attempts, I found that when Directional Light exists, there will be an error related to light loading.

from: Menubar.File.js:126
Unhandled Promise Rejection: TypeError: this.light.target.updateWorldMatrix is not a function. (In 'this.light.target.updateWorldMatrix( true, false )', 'this.light.target.updateWorldMatrix' is undefined)

Reproduction steps

• Create a Directional Light and add a cute little square
  
• Save JSON files
  
• Refresh the page and use the Open menu to reopen it

Code

This is the saved json for reference.
PS: In order not to make the issue very long, I didn't format it.

Seems to be a regression of #28696. I have a look.
