My hexacopter crashed!

Hallo to all, today a had a bad day after my Tarot X6 with pixhawk crashed. I had 2 successful flights with very stable loiter and very nice flight, but in the middle of last flight I lost my telemetry and I tried several times to reconnect, I was using tower app on androind phone, but after few times trying to reconnect, my hexa suddenly flipped and fell down like a rock. I really can’t understand what is the problem please can someone read my log file and explain the reason? My full setup pixhawk clone (hkpilot32) with gps m8n. Motors tarot 5008 340kv with dji 17X6 folding props and 6s 16000mah multistar battery.
