I'm inclined to believe that the pipe won't enter the EOF state until
the target command terminates (then the top-level cmd.exe). The target
command likely terminated prematurely due to an error before priting
any output.

If we append "2>&1" to the command line, we can capture the error
message through the returned pipe if any. Such error messages will
cause the subsequent code to fail with an error such as "unexpected
string: 'the output'". I'm not sure, but if this is permissive, the
returned error messages could potentially provide insight into the
underlying issue, paving the way for a potential solution.

regards.
