@felix007 Did you manage to find a fix? I am randomly getting this problem where the HKLiveWorkoutBuilder seems to get stuck and beginCollection NEVER receives the callback. It’s very weird that we cannot force-end any current HKWorkout session that might be corrupt so that beginCollection can start again. Usually restarting the device fixes the issue, but not always.

I have tried with the recently launched Xcode 14.4 beta, but still not working. This is so broken

I am experiencing this problem too. Xcode 15.2 and 15.3 tried. WatchOS 10.4. Tried everything. Nothing works :)

Still not working using Xcode 14.3 and simulators on iOS 16.0+
