Does it happen always in the same place or is it a random function? It might be due to how the code is compiled in that exact context, or an interrupt that confused the internal debugger. You should be able to "step out", or just run and hit another breakpoint.
Thanks for the report, I will flag this for further investigation.
Thanks for the suggestion. We will try to improve the Debugging with IDE 2 tutorial by integrating some more detailed descriptions of the integrated features.
