Qt Creator must be restarted between each QML Profiler session

I am profiling apps running on Raspberry Pi 4 using QML profiler from the Ubuntu host. After running one QML profiler session, the QML Profiler menu item in the Analyze menu is disabled. Also, the Stop button does not change even if I stop the session. When pushing "Stop," the application closes on the device. See attached picture.

This means I must restart Qt Creator after each QML Profiler session.
