How can I fix this problem about the same key when I return to the hall ?

I found this problem because I placed a networkObject in the lobby scene and set it to DontDestroyOnLoad, when I returned to the lobby scene, it was repeatedly loaded，thank you!
I have another question for a long time. Can you help me look at it? This is the link。

Hi,
Please, provide more info about the steps you're doing.
I believe that the problem shows up when you're changing scenes, how are you doing it? what are you trying to achieve?

I use the "Runner.SetActiveScene" method to transfer from the game scene to the lobby scene, and this error is prompted. The question is, do I know which object the same key refers to? There are NetworkObject objects in both scenes.

Are you using any custom scene manager?
Changing scene should not give any errors, this error says that a NO that was already been passed to the runner is trying to register again. The previous scene is unloading correctly?
The question is, do I know which object the same key refers to?
Not sure what you mean here, but it's the object with the NetworkGUID:
621965f5-6748-4c40-926f-a09b03119bff, according to the error log.-----
