# Troubleshooting

### Can't build on platforms that Unity Hub reports as installed

On macOS, some versions of the Unity Hub don't install platform modules properly. This issue is fixed on version Unity Hub version 3.3.0. If you want to use a prior version, **install one module at a time**.

### BuildConfiguration assets missing defining script

SDK 0.9 release removed dependency to the experimental package Platforms. As a result, your existing BuildConfiguration assets will have its defining script missing. To recreate the Simulator build configuration with the new pipeline, you can do it from the Simulators Module in coherence Hub.
