3. If the USB is mounted, unmount it:

   sudo umount /dev/sdX
   

4. Write the ISO to the USB:

   sudo dd bs=4M if=/path/to/your/iso of=/dev/sdX status=progress oflag=sync
   

5. Eject the USB:

   sudo eject /dev/sdX

I have exactly the same thing. Created clone from latest Mint and made bootable disk with built in app - did not boot. Finally when I did try with Balena Etcher I got the same error.
