Workout being ended early?

I use the Systm app on my Mac to do cycling workouts. This week, though, the workouts are ending WHILE i’m in the middle of them. They then show up as “recovered”. In this example, the Systm app ended the workout after 28 minutes, even though the activity was longer, and i had intended to cycle for longer. Anyone else having this issue?

A couple of questions. What version of MacOS are you on? What system are you using and how are resources? I found that running with either low memory available or low disc space available will cause SYSTM to crash during a workout. If you can, free up some more memory space or disc space.
