flashing ubuntu 64bit image failed

Can anyone help me fix flashing Ubuntu using etcher failed to my micro SD card 128GB for the RPi 4B+? thank you so much for your help!

Hello, can you try flashing a different image file or re-downloading the Ubuntu one to rule out image file corruption? Also, you could try flashing the image file to a different SD card to rule out an issue with the SD card. Let us know if any of these options prevent the flash failure.
