[BUG] Getting "duplicate key" exception when installing Forge 1.20.1

[ItsTheSky]

Hi there, I'm getting the following exception when trying to install forge 1.20.1 with version 47.2.32:

An item with the same key has already been added. Key: Name
   at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
   at System.Collections.Generic.Dictionary`2.Add(TKey key, TValue value)

   at CmlLib.Core.Installer.Forge.MForge.Install(String mcVersion, String forgeVersion, ForgeInstallOptions options, Boolean forceUpdate)

Any idea what did I do wrong?
