Etcher broke my USB stick … or did it?

Hello, I am affraid you are very wrong. The software did kill 2 of USB keys when I tried to make bootable Endevour OS from the iso image.
The first usb was very normally functioning sandisk extreme 64GB.
Based on what I was reading about the problem - inability to recover the partitions, I bought a new sandisk 256GB usb disk.
After trying to make the bootable usb, I got exactly the same result.

DISKPART> clean

DiskPart has encountered an error: Access is denied.
See the System Event Log for more information.

so the Etcher DID KILL both usb disks.

Unbelievable. I am lost for words. The worst possible software ever.
