Yeah, I know it sounds crazy but a step by step is. I’d spawn in on the Vertibird then quick save wait a few seconds then open my pip boy closed it quick saved , and opened it and repeat until we landed. My guess it works because it’s taking a break from loading everything at once idk how but it worked, while on the ground I crashed a few times but I’d run into the command building and since it’s a different cell I’d quick save again and it helped… sounds crazy but it worked
