Docker build issue with server content: COPY --from=...server:10.0.20348.2529 C:/Windows/SystemResources/mfplat.dll.mun... failed to copy files: failed to copy file: open ...Windows\SystemResources\mfplat.dll.mun: Access is denied.

Describe the bug

Using the server files should work.

Errors like these will sometimes manifest as

failed to copy files: failed to copy directory: unexpected EOF

when one of the source/destinations raises an access denied error.

Minimal reproduction:

COPY --from=mcr.microsoft.com/windows/server:10.0.20348.2529 C:/Windows/SystemResources/mfplat.dll.mun C:/Windows/SystemResources/mfplat.dll.mun failed to copy files: failed to copy file: open \\?\Volume{19443b0d-864a-4f84-9f5d-2db512ad3877}\Windows\SystemResources\mfplat.dll.mun: Access is denied.

To Reproduce

Dockerfile:

FROM mcr.microsoft.com/windows/servercore:10.0.20348.2529 as final
USER ContainerAdministrator
COPY --from=mcr.microsoft.com/windows/server:10.0.20348.2529 C:/Windows/SystemResources/mfplat.dll.mun C:/Windows/SystemResources/mfplat.dll.mun

Expected behavior I should be able to copy this file from the server image.
