[Error] When I add dust particle, I Meet Error about "object are trying to be loaded during a domain backup"

I’m makeing 2d platform game like “angvik”.
To improve Movement & Jump System, I add “Particle System” for the dust effect when jumping.

Fortunately, I can enter Unity play mode and it works as I want.
But this error is popping up in the console window.
"Objects are trying to be loaded during a domain backup. This is not allowed as it will lead to undefined behavior!

UnityEditor.Graphing.GraphObject:OnBeforeSerialize()"

I heard that it may cause abnormal behavior, so I did a lot of research, but I don’t know exactly where the error occurred.

In a project that was already running fine (this error didn’t appear), I just added dust particles, so I’m still checking the code where I added the dust particles, but I’m not sure what the big problem is.

If you have ever experienced a similar problem and solved it, can you tell me how you solved it?
