Failed to create SimulationConfiguration (Unity 2023.2.5f1)

[TheArrivalGames]

I imported PA into my unity Project, did the basic setup, assigned my objects (1 Terrain, 30+ meshes) and assigned materials. When pressing the "Calculate" button in the Probes tab i get the Debug.Log

Failed to create SimulationConfiguration UnityEngine.Debug:Log (object) Microsoft.Acoustics.Editor.AcousticsProbesTab:LogMessage () (at Assets/Acoustics/Editor/AcousticsProbesTab.cs:406) Microsoft.Acoustics.Editor.AcousticsProbesTab:Update () (at Assets/Acoustics/Editor/AcousticsProbesTab.cs:433) Microsoft.Acoustics.Editor.AcousticsEditor:Update () (at Assets/Acoustics/Editor/AcousticsEditor.cs:176) UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

As well as

Did i miss a step during setup?

I have the same issue. Sometimes it works and sometimes it doesn't. No help anywhere.

I fixed it by adding a navmesh to my terrain. Have you tried that ?
