Early access rewards are gone, so please tell me how to restore them

Leaving the first world where there was early access compensation, there is no certification compensation in the second world.
Leaving all the worlds to solve and deleting all the characters won’t get a certification reward.
I want to know how to reset all progress and I want to get early access rewards and Twitch Drops rewards again.
If you know a solution in this regard, please let me know.
