According to the specification page you linked to, the board has a ICM20948 IMU sensor, not a MPU9250. The library is failing where it's trying to initialize a AK8963 magnetometer, which you maybe don't have

what does an i2c.scan() tell you? An MPU-9250 has a default I2C address of 104 (0x68), while the default I2C address for the ICM20948 is 105 (0x69).

I was mistaken about which example program to run, I was able to get the results by running icm20948.py.

This was extremely helpful ! Thank you very much !
