Unanswered Questions only show for admins
Apart from the customizations you described (within your "customizations I have made ..."), you also seem to have customized the 2nd (last) filter that you're using: it says "(in Answered ...)", while in your exported view it shows the machine names of content type "Question" and content type "Answer". While the view shipped with the Answers module (disclosure: I'm a co-maintainer of it) uses ONLY the "Question" content type.

I suggest you adapt that 2nd filter back to how the shipped version looks like, i.e make that filter only check for nodes of content type "Question". And if you then need any other data (columns in your view) specific to the "Answer" content type, those should be made available via the 1st relationship (entity reference) you already have in place (and which still matches the shipped version).

I'm not yet sure if this is the only change you'll need, but at least it will get you closer to the view you're trying to create (depending on possible updates to your question, I might further improve my answer afterwards).

PS: I noticed you also turned of "aggregation" (another customization). Not sure (yet) if that has anything to do with your issue.
