[Having issues with trying to launch Battlefront 2 Mods with Frosty]

Hey, I searched this up and I'm sure this question has been adressed before but I didn't find any working answer. I put some mods in my Frosty Mod Manager to run Star Wars Battlefront II, and I get the "Object reference not set to an instance of an object." issue. More specifically, what you'll see here below:

 

Object reference not set to an instance of an object.

at System.Threading.Tasks.Task.Execute()

If anyone could help me, I'd be very grateful.
