sandisk cruzer usb drive

Good morning everyone, my usb drive is driving me crazy. I placed a iso file of windows 10 on it in order to install windows 10 on a pc. Now i’m trying to revert the drive back to just being a stroage device but 1. Mac book doesn’t recognize it when plugged in 2. When i use disk utility to try erase it i get an error…iv’e tried all sorts of commands that i googled online but nothing changes. I just wanna get my drive back to normal as a storage device plz help.
