I installed the library without smbus2 at first and it was running fake smbus correctly. After I installed smbus2 the example code stopped working. it gives an error 121. what should I do?

I have exactly the same issue. Can't really tell what's going wrong here.

I found out that I bought a fake sensor. A friend of mine gave me one that he used in his RC car a while ago and it works now. I think that Amazon sells some crappy stuff.

Yeah sucks about the hit/miss of sensor quality.
Especially when they're not really cheap at $14 ea.

@JafetSalgado the magnetometer address is 0x0C and don't appaers in the image of terminal you send here.

Maybe you burn it pluggin the sensor in 5v?

I did the same thing (plug the MPU9250 in 5v) and burn just the IC of magnetometer.
