ParameterControllerView.CreateSearchParameterList NullReferenceException

Unity Engine

Whenever I open an existing project or create a new one I’m getting this error:

NullReferenceException: Object reference not set to an instance of an object

Hi!

We are aware of this bug and are working on a fix. For now, simply reset your layout and the problem should be gone.

cheers.

Thanks for the quick reply. Reverting to factory settings does indeed fix the issue, after you restarted Unity as well.
