Same problem. Recently changed themes and now my archive page no longer lists posts. Archives work fine in the sidebar widget. I reactivated other themes to see if the archive page would repopulate and some of those worked as expected, some (I believe the newer themes) would not list posts on my “archive page”. Also the template box does not appear when trying to edit the page or recreate it.
Additionally, the next page/previous page is not functioning. Clicking “next page” produces a url of “page 2” but the actual content does not change.
