Xcode 14 unit testing clone simulator

In Xcode 14, running unit testing seems to be creating simulator 'clones' (named 'Clone 1/2.. of iPhone'). On older machines, this can take a long time. This is happening every time when switching from running the App and running tests. For example, running the App will launch the Simulator. Running tests will launch new one or more Simulators (Clone of ...), and running the App again will reload the original Simulator.
Any way to control this? This makes running tests a real pain on older machines.
