Had a look at your flightdata, see my chart of your data
Many same warnings :
"Ambient light too low. Vision system and obstacle sensing unavailable. Fly with caution"
With full forward stick your Mavic Air2S is climbing without RC up input.
Speed is reducing and increasing few times, this could indicate that the OA sensors is seeing 'false' obstacles.
Seeing an obstacle will reduce speed, climb and go forward again to the old speed, and again and again.
But speed is also reduced full forward stick AND applying yaw input, this is also seen in your log (normal behaviour)
So hard to say wich one (or both) is causing the speed to drop a bit.And if your OA setting was set to "Brake", than drone should only brake at an obstacle and not climb.
Bottom sensor height did not measure any height, so this is not the cause of this unintented climbing. [ 10.9 is the last recorded height at 4.8 seconds in flight ]
Only strange value is that while climbing the vertical speed shows sometimes a negative number. (normally vertical speed follows the ascend or descend move)
I would suggest to calibrate the IMU * and fly again in normal day light, see if this happens again.
*First RTH height steady while vertical speed shows 0.2 up ! normally steady height flying = zero vertical speed
Second RTH steady height but vertical speed show minus values! up to 1.6 !
cheers
