Problems with the PM3100 sensor

Hi all!
Due to problems with magnetic radiation, I bought myself a PM3100 compass. I connected the ego via the I2C protocol and it immediately appeared in Mission Planner. I calibrated the ego the first time with no problems. The next day I tried to take off and my drone became very unstable on climb (there were errors due to magnetometer anomalies). Can you please tell me if the PM3100 needs to be calibrated before installing it on the drone? Or maybe I made another mistake?

No, on the craft. Use MAVExplorer and the Magfit procedure to calibrate it now:

This is the log file of one of my flights. All the takeoffs were successful, but during the landing there were anomalies of the magnetometer, and the drone crashed. Then I flew with GNSS here 3.

Hi all!
Yesterday I went to test again. I installed and calibrated the PM3100 compass. When climbing, magnetometer anomalies reappeared. I will leave the video of the flight and the log file
