Help analyzing crash log - EKF3 laneswitch1

Plane S800 WING / FC Matek F765-WING, with GPS and Compass / Arduplane ver 4.1.7

Hello all,
I would appreciate some help analyzing a crash I had recently.

The flight progressed as such,
Take-off in FWBA and switching to CRUISE with no problems.
Then the plane began to roll to the left and it didn’t seem to respond to rc inputs anymore.
Switching to MANUAL I was unfortunately, not able to safe the plane and it crashed hard into the ground.

I’ve flown the plane for some hours now, without any similar issues.

Looking at the log I notice an initial message about EKF3 lane switch1 and later there are several messages regarding EKF3 IMU0/1 yaw aligned to GPS velocity followed by several AHRS: DCM active and AHRS: EKF3 messages.
I although think the last messages were logged after the plane crashed.

Can someone have a look at the log and see whether there was some obvious fault that triggered the issue?

I’ve uploaded both the log from the crash as well as a log from a good flight a week before, to my Google drive. No parameters/physical changes were made between the flights.
