Why can't I access artifacts in a new DNG 6.0.4 project?

When I try to access the (empty) artifacts section in a project I create in DNG 6.0.4, it never loads them and I see it giving me a warning and an error about the new project I just created not having a component because it maybe predated components.  it doesn't even provide an error code to reference.  This was a DNG instance upgraded to 6.0.4 from 6.0.2 and the other actual pre-existing projects all work fine.

Am I missing something?

The log I see is:

“WARN - Unable to retrieve component information for <project>.  The parent project <project> may have existed before Components were enabled”

“ERROR - Invalid or incomplete well known type cache encountered for component <URI> because <null>.  Skipping well-known output, Content discovered is ‘list of existing public types with ERROR prefix’”
