Sorry, but I'm new to this type of stuff, so Idk what it means to launch the game through or run the exe directly

I did what razazel suggested and it didn't work

Okay, the mod that I'm using is the SOF WWII mod pack and everytime I try to launch with it, it says "Launcher has detected that Arma 3 was closed unusually and it gives me the exit code as 0x0000DEAD-
