Getting error when flashing image

I am trying to flash image from https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial/releases
I tried to flash both the first and second images .img.xz
I have a Windows 10 host computer and a 512GB SSD
It is giving error


I also tried by starting balenatecher in admin mode and the same issue.

Please help

Hi Thalanayar, if you have indeed launched Etcher with Admin privileges, then that message is odd. For troubleshooting purposes, can you try downloading and running the Standalone version of Etcher, which can be downloaded via the Etcher website here: balenaEtcher - Flash OS images to SD cards & USB drives. (Click on the drop-down menu, and select “Etcher for Windows (x86|x64) (Portable)”.

Once it has finished downloading, double click to launch it. Try again to flash your image, and see if that works better for you. Thanks!
