i was trying to flash this file “Hackintosh Zone High Sierra Installer.dmg” windows pc, the flash process failed. and the usb stoped working. i tryed the disk management utility it showing readonly with a reduced capacity of 28GB. when i tried BalenaEcher to flash again it showing that the usb drive is locked.
That sounds like a broken USB stick to me. You can try to delete all partitions in the disk management, but I wouldn’t get my hopes too high.
If this was a cheap USB stick it’s also possible, that the 32GB were fake and the flashing tried to write to non-existing space
