I have seen the logs and Roll / DesRoll, Pitch / DesPitch are almost identical so the drone wanted to do those movements to fight against the wind. Maybe the PIDs are very agressive, I would suggest you to do an autotune but there is a bug in AC 4.0.

And I think that you are using Dshot or OneShot, because RCOU C1, C2… show a signal between 125 and 230 (I am not familiar with those protocols) so try to use PWM to control the ESC.
