You’ve set up a paradox, then identified it as a paradox.
If you’re the one setting up the thought experiment, and you’re okay with including made-up elements like Omega and infinite hell and memory erasing, then go ahead and introduce other made-up elements that resolve the problem. “Therefore, SuperUltraOmega figured it out and went back in time and fixed it. Ipso facto presto chango.”
If you can find this or a similar paradox outside of a thought experiment, you’re onto something.
