Same here. In addition, when I opened Console, there were a constant stream of Xcode errors similar to this:
"found no value for key DVTShowAllSimulatorRunDestinations in CFPrefsSearchListSource<0x600000679780> (Domain: com.apple.dt.Xcode, Container: (null))"
Switching off the "Execute in parallel (if possible)" option helped to run tests, but the errors stream in console didn't stop.
Xcode Version 15.0 (15A240d).
