After a week (maybe over 20 hours). I finally got Open Media Vault sharing a network drive to my Windows PC. It was totally worth it because it's great but in attempting to resolve I had to 'upgrade' to Windows 11... which didn't work. Reset my bios to defaults... This stopped windows booting altogether. Wipe my PC and install Windows 10 fresh which finally worked. I think it would work seemlessly for 90% of people who try it so don't let my horror story scare anyone off. Open Media Vault is great and well worth checking out of you want a relatively cheap highly customisable disk drive that's on your network and accessable from any device (except a worn out install of Windows). You can even install Plex on it which is my next project!
