Editor Error: [Scene] component already added

Cocos Creator
#1

Hi.

I’ m using Cocos Creator version 3.8.2 currently.

I imported assets packages exported by Cocos Creator version 3.4.2.
And scene and code work fine in play mode.

However, sometimes the editor show this error after editing source code (after displaying ‘script compilation in progress’ at bottom right of the editor).

Is Bundle

I tried to rebuild the scene hierarchy step by step.
However, I was unable to determine when the error occurred.

What could cause this error?

You can try using Cocos Creator version 3.4.2. This problem may be caused by version incompatibility

I got the same error also version 3.8.2, I don’t know how to fix it, and why it appear???

I too suffer from this symptom.
The version is 3.8.2, same as jpHuang.

Me too. I keep getting the error despite everything being fine! I wish this were fixable.
