I have tested the workflow, and with some modifications, I am able to create a copy of the file I want in a new destination folder.
Thank you. I am marking it as a ‘solution’.
My wish for this was to find a workaround while waiting for this bug to be fixed. But unfortunately even with this workaround, re-opening a saved workflow still resets every downstream nodes. I guess waiting for the bug to be fixed is all I can do at this point in time.
