I was finally able to figure my issue out, while the Rage Plugin was trying to load the story mode, it was stuck in a cutscene/mission in actual GTA5. To fix this, I loaded up regular GTA5 and played through to a point where I was in free roam and it resolved that issue. Could be something you might try as well, however, my error messages were completely different. Worth a try though.

I'm having the same issue, however, in my console, the only warning I get is: "Path without extension: lspdfr/data/custom". It seems like it's not finding the xml files for regions, backup, agency, and inventory.
