Jupyter is not working properly

[Larz60+]

The only suggestion I can make is to reduce all of the code to only the part that creates the 1 minute intervals
by itself with a dummy function showing time and iteration number

Then see if it still auto-terminates.

You can also check the call stack (on just a few iterations), to see if there is something odd happening.
