Assertion failed: ActorInfo.SharedWorld

Assertion failed: ActorInfo.SharedWorld

This is the error content.
I am implementing what I understand about GameInstance.

There is a component that manages stats.
When a stage is cleared, ClientTravel is called.
Before moving the level only the values ​​to be maintained were saved in the GameInstance in the form of a struct, and then the values ​​were received from the component again after moving the level.
There was no problem when testing without changing the value, but when the value changes, the above crash occurs when moving the level. Do you know how to fix it?
Also, is it correct to use GameInstance for this purpose?

Changing the value did not cause a crash.
Occurs when you click the outliner and move the level to see if the value has changed.
But I don’t know why.
Occurs when click any Actor in the Outliner.
Does anyone know why this is happening?
