Crash: Log Review Help

Would greatly appreciate log review Help. First flight after a long journey trying to learn setting up S 500 quad, Pixhawk 2.4.8, apm copter 3.5.7, MP 1.3.58 , 3 S, . Have a lot of bench log errors, bad logging, compass, Gps… This flight not real stable tried to switch flight modes did not get what i expected, drifting away switched to RTL and it went down. I may have lost my cool and may not have let RTL have full command, (reduced power???).
Thanks for any help available. Ken
