C++ Transition Guide for 5.4

Development Programming & Scripting
8

I have a C++ project that I’m upgrading from UE5.3 to UE5.4. Its not compiled from source, just using factory fresh UE5.4

When compiling my project, I’m getting:

UE_5.4\Engine\Source\Runtime\Experimental\Chaos\Public\Chaos\ImplicitObjectScaled.h(1129): error C2760: syntax error: ‘const’ was unexpected here; expected ‘expression’

Its coming from this function inside ImplicitObjectScaled.h:

template<typename T>
const T* UnwrapImplicit(const FImplicitObject& Implicit, FVec3& OutScale, FReal &OutMargin)
{
	OutScale = FVec3(1);
	OutMargin = FReal(0);

	if (const TImplicitObjectScaled<T>* ScaledImplicit = Implicit.template GetObject<TImplicitObjectScaled<T>>())
	{
		OutScale = ScaledImplicit->GetScale();
		OutMargin = ScaledImplicit->GetMargin();
		return ScaledImplicit->GetUnscaledObject();
	}
	else if (const TImplicitObjectInstanced<T>* InstancedImplicit = Implicit.template GetObject<TImplicitObjectInstanced<T>>())
	{
		OutMargin = InstancedImplicit->GetMargin();
		return InstancedImplicit->GetInstancedObject();
	}
	else if (const T* RawImplicit = Implicit.template GetObject<T>())
	{
		OutMargin = RawImplicit->GetMargin();
		return RawImplicit;
	}
	else
	{
		return nullptr;
	}
}

Not sure how to get around this or why it would be failing to compile this?
