Crash detetion - what caused it?

Hi all,
Hopefully somebody can help me figure out what is causing my plane to crash.
Im not an expert in log analysis. It has happened three times, every time when fighting against the wind, groundspeed 3-5m/s. (I have no airspeed sensor). Im not sure it has anything to do with it, but it is the only thing I have observed that is common.

First, I see the “ERROR POS VERT VARIANCE” / “ERROR VELOCITY VARIANCE”. Then it says, “crash detected” and “disarm”. Motor stops and I have to glide it to the ground.
Any thoughts or advice would be great! Thanks
