That helped, thanks Louie. I've restored all of my game saves to OneDrive and I'm back to where OneDrive is telling me that I'm running out of space. However my game no longer recognizes those saves as being there.
So the next problem is how to get my game to see those game saves. Looking at my Game Saves folder all of my saves are there, but OneDrive used to be there instead. Apparently deactivating OneDrive got rid of it.
The follow on problem is dealing with the OneDrive space issue. There is no way in hell that I'm going to start paying Microsoft to expand the space on OneDrive when I have 15 TB of free disk space on my computer.
