You have just posted the same link as before. The commands that you are trying to execute by WinSCP have wrong syntax. You have way too many double quotes there.
It looks like you have used batch-file syntax in WinSCP script file (though that's just a guess, as we still do not know how you are executing WinSCP).
The script file should have a syntax like shown in the example:
https://winscp.net/eng/docs/scripting#example

There have remote like.

You didn't show us how you provide the commands to WinSCP.

Attached is what I got from command line:

Following is my Env
Windows 10 x64
WinSCP version 5.13.6 (Build 906 1)
