MPU6050 code hanging

Hello, have a nice day,
well yesterday I was trying to solve a problem when suddenly I got a worse problem, the past three days, I was using Arduino Leonardo with MPU6050, it was detecting everything so well, and I could show the result with processing software, but suddenly, it stopped working and always hangs at ""Initializing I2C devices..." which means it doesn't execute the next function:

mpu.initialize();

(I'm using the MPU6050_DMP6 code).

anyway I tried different computer with different OS, different Microcontroller, different MPU sensor, it always gives the same result... I am really lost.
I tried to find same issue online, but it doesn't seem to help so far.

Try here.
Get back to us when you've read it.

I guess there is only one code for MPU6050_dmp6
