What can I use to check binaries for nativization code?

Hello,

I am currently trying to get success with Nativizing a few Blueprints but it is not wanting to work since I started to use GameSparks.
But I managed to get a successful build in the end (with a slight hack) but the packaged game is broken and the blueprint I tagged for nativization does not even want to spawn.

It seems to me like the code is not even there. Is there some way to confirm that the compiled and linked in asset is actually there?
I tried DependencyWalker on the final .exe but I cannot spot the nativization plugin or the blueprint anywhere.

Does anyone have any ideas I could try?

Cheers
