Just wanted to add that I was getting a similar message also due to having two pathfinder components enabled at the same time, on two different game objects even though one was disabled.
I had one in my menu scene, then another in my main gameplay scene which is loaded as an additive scene.
I was disabling the menu scene gameobject that had the pathfinder component. This doesn’t disable the pathfinder. I then tried disabling the pathfinder component. This also doesn’t help. I had to delete the component from the scene. I posted a new question about if/how to have multiple pathfinder components across multiple additive scenes:
Can you have 2 pathfinder components across different scenes?
Note that I didn’t get any errors or warnings when either the GameObject or pathfinder component was disabled.
