Have your tried switching off all wireless options first, before launching the app @dazer2000 ?

DJI GO4 app crashing when trying to update firmware

Yeah I had this problem. As soon as the Mav connected to the RC it shut down the app. Very weird, seemed to have something to do with Mav GPS because it worked OK inside, and when I left the area (pyrenees) all was dandy. Oh and something else to try, put phone in airplane mode to shut out external influences.
