Failed with unexpected EOF message while build -t

Hey Friends.
I’m using VS Code, docker extension has been added. for Learning Docker I wrote below code which need to be build
FROM mcr.microsoft.com/windows/servercore:ltsc2019
ADD https://download.UiPathStudio.msi C:\UiPathStudio.msi
RUN C:\UiPathStudio.msi ADDLOCAL=DesktopFeature,Robot APPLICATIONFOLDER=C:\TestUiPathForDocker
CMD [“cmd”]

At first I was having an error
=> ERROR [internal] load metadata for [Window Server Image] (I’m new user so not able to use the link which is used in “FROM”)
So I switch to windows container.
Then build get started It was downloading few files and unexpectedly it stopped and unexpected EOF message occurs

Many thanks
