write protected 256GB sandisk ultra usb 3.0

it says theres a problem with this drive when i insert it into my pc but i cant fix anything because when i try to repair the drive it says its write protected and i just got it and didnt change any settings or anything and i looked up online how to un write protect a usb and i did all the steps on all the websites and nothing fixed it, please help i spent like 50$ on this thing.

Quickest fix is to return it to the seller for a replacement.

ok thanks
