Script attached to '_PlaneThatCallsIntoPlugin' in scene '' is missing or no valid script is attached.

I keep getting this error but all i got in the scene is a cube, i dont know what to do, i get this error and another one talking about the script of a ‘Sphere’ that i also dont have in the scene,Script attached to ‘Sphere’ in scene ‘’ is missing or no valid script is attached. I keep getting this error on unity, but all i have in my scene is a simple cube, just for testing, i dont know what to do

Post a picture of your inspector, it sounds like you have a missing script on an object. If you select the object check the inspector, it should show a missing script component, you just right click and select remove.

The same is happening to me. This thing says that its a bug and that you should ignorit: Start Page

This is actually from the Windows Mixed Reality plugin.

The file is in com.unity.xr.windowsmr@4.6.2\Tests\Runtime\Resources\Prefabs

Unfortunately since it’s an imported package, you cannot modify the file. Perhaps Microsoft will fix this in a future release.
