Sorry for the delay. What version of Map Pilot Pro are you using? What kind of iOS device are you using? Please try to take a screenshot that is taken before you suspect it will crash so we can see what you are seeing.
Things to try:
Try putting it in Airplane mode.
Make sure all other drone related apps are fully closed.
Enable 'Auto Clear Image Points' in the 'User Interface' part of the Map Pilot Pro settings.
