Hi Paul,
Dear member of SanDisk Community, welcome.
Friend, please:
Inspect with a magnifying glass and a flashlight, the USB 3.0 plug of the UFD, and clean the pins,
with wire or eyebrow tweezers, etc., and with isopropyl alcohol (or also medicinal).
Also try, with a can of “compressed air” and a paintbrush, etc.
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.
If the above steps have not solved the problem please, back up your data and contact SanDisk Technical Support
who will replace the device if it’s authentic and is within warranty.

Luck, and then you tell us, what happened, please.
