Well this is an enviornmental problem... In the meantime Windows understands Unix slashes more and more, maybe a single slash at the end would work?

Since the "\\ " combination, or better written out below in the Unicode characters, produces
a single space that is treated as a part of the argument

Unicode Character 'REVERSE SOLIDUS' (U+005C)
Unicode Character 'REVERSE SOLIDUS' (U+005C)
Unicode Character 'SPACE (SP)' (U+0020)

does it work if you use four backslashes instead "\\\\ "

Unicode Character 'REVERSE SOLIDUS' (U+005C)
Unicode Character 'REVERSE SOLIDUS' (U+005C)
Unicode Character 'REVERSE SOLIDUS' (U+005C)
Unicode Character 'REVERSE SOLIDUS' (U+005C)
Unicode Character 'SPACE (SP)' (U+0020)

To further troubleshoot this I think there might be an error in the way
D:\a\_temp\58292c41-7f29-49bd-933b-fc51c78aa3ac.cmd or some other .bat file gets generated.

Definitely those commands should be run with CMD but not with an UNIX shell.

Can you ask it to run it under cmd?
