In #8232: it reports the same sequence—breakpoint hit, F10 exits the process, F11 produces an error, specifically on Python 3.10. A maintainer reproduced it and then explicitly [declined to fix it]. Its resolution is
NOT_PLANNED, not a completed fix. But since we are dropping support for 3.9, I think we should fix it.
