About a month ago me and my friend tried to play a origins gauntlet mod, which required you to use a script, the script didnt work for us but afterwards, even after deleting the mod i get a long string of numbers on the top left of my screen.

Not only that but when i start a zombies match during the very begin right after loading a bunch of things appear on my screen, it refers to the long string of numbers as a identifier and lists some otherthings about plutonium, a "Lui checksum" and a "csc checksum"

If anybody knows what this is and how to also get rid of it i would be very thankful if you told me.

Already, thank you for your time.

PS: Id link the mod i downloaded that caused the issue, but this is my first time posting so i cant sadly
You can find the mod under the youtube video by youtuber "Chrrism" which is called "Origins, but each round has a different challenge" the mod itself is called "T6 TOMB GAUNTLET" by github users Zi0MIX and mbahgatTech.
