So, I was able to run your RunUAT without any trouble, once I changed the location to match what’s on my computer. So hopefully that isn’t an issue you’re experiencing any longer.
Looking into the Pakblacklist issue you’re running in to, I was unable to find much information on it. However, I did find an [AnswerHub post][1] which has a suggestion that may actually help you. Please try their suggestion and let me know.
Thanks!
