Dark Deception: Monsters & Mortals usmap

[BonbonFazbear]

I tried using the program to get the mapping file for the game "Dark Deception: Monsters & Mortals", which was made using Unreal Engine 5.1, idk if I injected the dll incorrectly, but it created a usmap file, but whenever I try to use it in any program to check the files or extract them I keep receiving the error message "An unhandled exception occurred: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')"
