When you set up cross save, you chose Steam as your primary platform, which is why you cannot access your Xbox characters.
If it won't let you deactivate cross save, it's presumably because you recently bought silver. In any case, you will have to wait out the remaining time, then you can deactivate cross save. 90 more days after that, you will be able to reactivate it, should you want to do so.
