Hi , thanks for the response and the suggestions! I tried removing the whole SimCity file from both the OneDrive and the hard drive on the new computer, and re-adding a newly transferred version from my old computer to my new computer and that still didn't work. I also tried creating a new region and transferring the cities like in the video you attached, and tested it out both on the old computer and the new computer. The transfer worked on the old computer without a problem, but still didn't solve the issue with the region when I tried to open it on new computer. Not sure if there's something else I can try, it seems like this region on this particular computer just won't load for some reason.
