Crashes back to Xbox Series X Desktop

Not only do I have CTDs at LSZH, but I also have double (overlayed) graphics issue. I bought the LSZH pack and now everythign is double. But if i delete it, it gives me the MSFS original LSZH graphics, which are not as good as the add on. How can I turn off the LSZH pack and only have the add on activated? is this even possible?
