I've been using Xcode server for several years to run some UI tests for assurance quality. Even though it has some limitations and bugs, compared to Xcode Cloud, there is still a way to use it. In my case, it's mandatory, the UI Tests are running while connected to a local server application.
Since I've updated to macOS 13.3 and Xcode 14.3, the user configured to run the tests is reported as "Logged out" on the Xcode Settings window, even though it is, in fact, logged in.
Complete new install of the system, new install of Xcode and other tools : same results. I have a bunch of logs related to Xcode Server Builder in the console, but none is reported as an "error".
Do someone have the same phenomenon ?
