Hey @James46717 , sorry for necro-ing the thread, but I am the folk behind https://github.com/tomjorquera/pico-micropython-lowpower-workaround, and someone just pointed me to this topic.
I really like your version of the micropython code which handle clocks properly. Do you mind if I steal it back in the lib to share the improvement around? Hopefully it will help fix up issues people such as you encountered.
(strangely I do not have these issues myself when I test thing on my picos).
