Need Help with Not Starting Up!

[EmpireMan001]

Hello everyone, I am sorry if this is the incorrect way to ask for help but here is my issue. This is the text I see pop up on my screen when I launch Star Wars Battlefront 2 from Frosty Mod Manager -

 

"An item with the same key has already been added.

at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)

at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)

at FrostySdk.Managers.AssetManager.ReadFromCache(List`1& prePatchCache)

at FrostySdk.Managers.AssetManager.Initialize(Boolean additionalStartup, AssetManagerImportResult result)

at Frosty.ModSupport.FrostyModExecutor.Run(FileSystem inFs, CancellationToken cancelToken, ILogger inLogger, String rootPath, String modPackName, String additionalArgs, String[] modPaths)

at FrostyModManager.MainWindow.<>c__DisplayClass14_0.<launchButton_Click>b__0(FrostyTaskWindow task)

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

at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)"

I have no idea what any of this means or how to fix it (I am very new to modding my games). Any help would be greatly appreciated!
