ICM20948 magnetometer issue


I am develloping product witch ICM20948 and need to use magnetometer. I tried to move some existing and working code for arduino. I was able to get data from magnetometer. But next day when i tried the same thing, magnetometer wasnt responding. Just sometimes it ran for a while. In datasheet I founded that reseting i2c master is possible, but after this reset it was working 50/50. Sometimes yes, sometimes not. Now it isnt working at all. I know that it has not much in common with Nordic but I completely ran out of ideas. Please, could someone help me? I thing the problem is in the i2c master, but now also resseting it doesnt work. I could try post this issue to Stackoverflow, but they immediatelly mark this question as non related to programming, so I am asking you.
