I would like to bring up my case in detail as well since it very similar
I have pretty much exact similar error on two differnt quad frames and motor/esc setups, two different m4n4 setups, on different firmwares (1852 and 1923)
I have done many many flights overall and this error is very present all the time
what is so disturbing is that the everything works so well and then you get basically slapped in your face
now I wanted to try a fresh restart and went back to the the 1852 fw and reset the params and did a pid tuning until I was happy with the flight performance
I had a very clean flight for 10min which I uploaded the log...tested atti mode and gps hold
the next flight I had 2 moments where I could hear again the very familiar sound of the quad doing erratic motor outputs without stick input in atti mode, I continued flying to see what would happen and then it flipped aggressively upside down
there was no wind
these are the 2 logs

I am happy on all kinds of help, maybe you can spot something I have missed so far
these two m4s are the first AQs I have set up
