This issue seem to be connected to the results_loader dispose()

Sentry Issue: ENTITLEMENTCARD-APP-1M

_Exception: Exception: A PagingController was used after being disposed.
Once you have called dispose() on a PagingController, it can no longer be used.
If you’re using a Future, it probably completed after the disposal of the owning widget.
Make sure dispose() has not been called yet before using the PagingController.
