So just to add to this, I have literally just installed Windows 2004 version from within 1909 using the Microsoft media creation tool and choosing update this PC now, and it worked fine, I then used the same tool to create a Windows 2004 USB so that I can clean install at a later date.
I think sometimes the creation tool may fail if you use it on a front USB port or a USB hub, try using a rear (direct to motherboard) port and try a USB 2 port rather than USB 3.0 if you still have issues.
