Docker Buildx fails to create builder in Windows

Question

I want to create a multi-architechture (Windows/Linux) image. I can't do this with Docker Desktop in Linux Containers, because it fails the build when it comes to Windows specific commands in the Dockerfile.

So I run Docker Desktop in Windows Containers. But when I want to create a builder with buildx, it fails without showing a reason. It just says => ERROR [internal] booting buildkit. But if I continue and try to build the image, I get the same error again but with some extra info: [internal] booting buildkit: ------ ERROR: Error response from daemon: Windows does not support privileged mode.

Here is some output to show my situation:
