Manage User Page Times Out On Fresh Install

On a fresh installation, in Kubernetes from the 8.20.0 Docker image, visiting the Members or Auth page results in a timeout. Other pages within the UI function normally, and a monitoring application which creates errors every 5 minutes functions fine, but not being able to manage users from within the app is a problem. Has anyone seen this behavior before? Are these two pages unusually expensive compared to the rest of the app?
