Sometimes, USB memory sticks that have been used for creating OS installation media may have a corrupted partition table, making it impossible to format them using the "Disk Utility" app.
You can easily format it using a command:
sudo diskutil eraseDisk FAT32 USBMEMORY MBRFormat /dev/disk2
Additionally, it's a good practice to compare the output of diskutil list before and after connecting the USB memory stick to determine which path it is mounted on.
