Yes, I've tried using a different phone and it works fine.

I've tried disabling the tpu_end_scenario() call, which avoids the
crash. My understanding is that the new settings are not activated
without this, so I guess a good spot would be to add some delays
directly after the tpu_end_scenario() call to see if the crash happens
within the interrupt handlers?

I'll give that a try.
