UE_DEPRECATED(5.1, "Compiled-in property constructor is deprecated, use other constructors instead.") FBoolProperty(FFieldVariant InOwner, const FName& InName, EObjectFlags InObjectFlags, int32 InOffset, EPropertyFlags InFlags, uint32 InBitMask, uint32 InElementSize, bool bIsNativeBool);
should be replaced by
FBoolProperty(FFieldVariant InOwner, const UECodeGen_Private::FBoolPropertyParams& Prop);
and other properties are in same.
