As a Docker community, we don’t see diagnistics. You can share the ID on GitHub
My only idea is removing the destination “DockerDesktop” folder before the attempt of moving the disk image. But I remember many reports related to moving the disk image on different platforms. There were issues on macOS as well, and I don’t know what is the current status of this feature.
If nothing else works, you can try to stop Docker Desktop, move the original the “DockerDesktop” folder to a new location, and create a symbolic link at the old location pointing to the new location.
