Western Star 6900 disappeared on “No country for Old truck”

I was playing no country for old truck and after recovering to my garage to refuel and get another truck I went back to repair the western star and it is now gone. I was driving the fleet star when it happened. I have tried restarting the task multiple times and it won’t even let me restart it.71414AF1-49B2-4413-859B-6807C85F2CE2.jpeg

I have the same problem the truck is gone and not not letting me restart the mission or spawning the truck. Any update?
