HDRP + New Inputsystem + XR = No Dev builds possible

Hi Everyone,

Today I stumbled upon something that I can only believe to be a bug.
I have a project in Unity 2021.1.20f1 using HDRP, New Inputsystem and XR (SteamVR). So far this worked great in editor and release builds but today I decided I finally wanted to optimize the fps and tried to make a debug build.

After succesfully building the screen stays black and I get this error every frame

NullReferenceException while resolving binding 'Enable Debug:ButtonWithOneModifier' in action map 'Debug Menu'


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

As far as I can tell the class responsible for this issue is Debug Updater + DebugManager.Actions.cs which is split between CoreRP and HDRP and mostly relevant for opening the SRP Debug Menu (which I don’t need but as those are in packages I can not easily remove them).

Does anyone have any advice on how to fix this?
