Windows 10 - Junction/Symlinks Broken (sometimes)

[RankWinner]

I've been using Junctions/Symlinks for years to help save space/speed things up by moving folders to and from my SSD's to a larger HDD.

Recently for some reason all of my Junctions/Symlinks going to and from my D drive have stopped working. Creating the link is fine, and the linked folder opens, but nothing inside is accessible, giving the error "The system cannot move the file to a different disk drive" when trying to open anything. If I try and create a folder or file I get a Catastrophic Failure: 0x8000FFFF error.

Right clicking and checking the link properties shows that the first link is fine, but when looking at the properties window occasionally COM Surrogate stops working.

Thinking this was an OS problem I ran sfc /scannow, chkdsk and multiple DISM checks/repairs but none of those fixed anything.

Even more confusingly I am able to create working links to and from other drives, it's just when using the D drive that this error occurs.

Posted this on overclock.net, one person replied saying they had the exact same problem, posted on reddit /r/techsupport and nobody replied there ;(

Does anybody know what could be causing this? If it's an OS problem then doing a clean install might fix it, but if it turns out to be a problem with the drives (which wouldn't make much sense to me, as only certain links between certain drives don't work) then that wouldn't help.
