Rpi4 < $(community_build)

Hi
I am trying to write the disk image file to a new SD Card and it's not working. (rpi4.64-snapshot-25261-2.7.15-2-r15599-ext4-fac.img)
Win32DiskImager shows completed but nothing is written to the sd card.
I tried balenaEtcher and a message popped up saying the image is missing a partition or is not bootable/ compatible. Same error with Rufus USB tool. Tried with ImgFlasher and also doesn't work.
I tried SD Card formatter till 95% then cancelled it as per instructions here; RPi4 step-by-step set up: please help - #11 by stargeizer
can someone please advise on what could be the problem?
