DS field with views block not displaying for anonymous users

I have a display suite field that's displaying a views block on a content type.

Is it custom code? Or a block field? I really need more context here as I need a good way to reproduce.

This is a display suite block field that is rendering a views block.

We were able to solve (or work around?) this issue by removing an unnecessary relationship from the view. So it's possible that this is unrelated to DS.

Thanks for coming back on this! I'll tentatively close this for now then since it works :)

Don't hesitate to open up again if you encounter other places where it might not work of course.
