Error when loading zombies

[LBacon]

Hi, recently whenever I tried to play t6 zombies I've been getting this error-

I haven't used GSC Studio since November 2020, nor do I have it in my files anymore so why is it just now giving me this error? It's probably a simple fix, but I wanted to post this on the forums before I screw up my game.

LBacon Maybe outdated GSCs or broken GSC files. Try to clear all your GSCs, start your game and if everything is working fine reinstall them one by one to see what could be causing the issue. Make sure to re-download them from their topic to get the latest version.
