I'm not familiar with the newer projects interface, but I've experienced a similar issue with the older Site Admin (/siteadmin).
The issue that I've experienced seems to occur if any piece of content (at least top-level content, possibly even nested content) becomes "corrupt", by missing it's jcr:content child node. If this is the same problem, you should be able to explore the repository with CRXDElite (/crx/de/index.jsp#/content) and either add the missing jcr:content nodes, or delete any content nodes that are missing their jcr:content child node.
