Hi Vincemiquel,
Dear member of SanDisk Community, welcome.
Well, with a powerful magnifying glass and a flashlight, review the USB 3.0 port of the PC, and plug of the pendrive.
Check, that the pins (Standard has 9 pins, 7 for USB 3.0 + 2 for USB 2.0), are not dirty, bent or broken, or simply not fit as it corresponds.
