I am working with indoor drones, and since GPS does not work indoors, I am using a Livox Mid360 LiDAR for position estimation. However, I am facing an issue where, upon takeoff, the drone becomes unstable and drifts to one side. I change different parameters but the flight behaviour is same. I have attached the log files below for reference.

I changed the following parameters but didn’t have any successful resutls
