Docker build of windows image hangs during RUN step

Docker image build lasts forever and CPU usage is 0%.

Build command:

docker build --no-cache --progress=plain -t harness/err_tracking_build_ex:latest .

The Dockerfile content:

# escape=`
# Select the required Windows Server Release:
FROM mcr.microsoft.com/windows/servercore:20H2

# Restore the default Windows shell for correct batch processing.
SHELL ["cmd", "/S", "/C"]

RUN `
    # Download the Build Tools bootstrapper.
    curl -SL --output vs_buildtools.exe https://aka.ms/vs/17/release/vs_buildtools.exe `
    `
    # Install Build Tools with the Microsoft.VisualStudio.Workload.AzureBuildTools workload, excluding workloads and components with known issues.
    && (start /w vs.exe --norestart --wait --quiet --nocache `
        --installPath "%ProgramFiles(x86)%\Microsoft Visual Studio\2022\BuildTools" `

        --add Microsoft.VisualStudio.Workload.ManagedDesktopBuildTools `
        || IF "%ERRORLEVEL%"=="3010" EXIT 0) `
    `
    # Cleanup

(Stuck in the last row forever)

I also tried without --no-cache but it didn't help.

Any suggestion?
