Hi @bensutherland, just let you know that we have been able to reproduce the issue in house, so thanks for letting us know. Whilst the new input system in preview, we cannot prioritise a fix for this right now but will be looking at this possible conflict for future releases of the Unity Engine.
That being said, we suspect the compilation errors may be overcome by reworking the sample scripts as there should be no conflict between the API’s.
Hopefully, you are able to work with the older inputsystem for now and apologies for any inconvenience caused.
