Apm 3.2 ERROR_SUBSYSTEM_MAIN

Hi Guys…

today it happened again… i was flying and then suddently i had no control anymore.
It landed failsafe and then took off again and finally landed. I even turned off the remote for a while but it didnt change anything. I was lucky nothing broke!

Flying a 250 with apm 3.2 FPV.

Can somebody please help me with the log?

Thanks!
