problem sensor IMU 9 axis GY-955 AHRS with kalman filter

I got a problem with the GY-955 sensor, I tried using the code given directly by Kriswiner Update BNO_055_Nano_Basic_AHRS_t3.ino * but what I used was Arduino Mega2560, I changed the pin to 18 / tx 19 / rx and I switched to 20/21 / scl but still doesn’t respond, where is this error,

or maybe I’m wrong in the library i2c_t3.h because the error that appears is in that direction

please help with this problem, thank you
