Expected the adapter to be 'fresh' while restoring state

Question

I have a viewpager2 with multiple fragments in FragmentStateAdapter. Whenever I try to open a new fragment and then go back to my current one with viewpager2, I get an exception

Answer 1

So my problem was that I was creating my FragmentStateAdapter inside my Fragment class field where it was only created once. So when my onCreateView got called a second time I got this issue. If I recreate adapter on every onCreateView call, it seems to work.
