Hi @massisenergy. We will look into adding Fedore 39 support for the builtin DB. We do support Fedora 40+

You can configure your own MongoDB connection to circumvent this issue. It is the recommended setup for regular FiftyOne usage as initial connections are faster (no subprocess required)

Same problem occurs on my Debian Testing (13) system in a venv.
