Spotify closes when starting runtastic activity

[BelgyBrown]

Hello, i noticed that on my secondary phone, which runs on android 6.00 (wiko sunny that i use for when i run), everytime i use spotify and gps, spotify closes, it happens especially with app that records sport activity (runtastic or strava). I did a reset, but the problem still exists: what can i do? It was working fine for months, but then now everytime i start spotify,  i open runtastic and start the activity: spotify closes.
