IL Compile Error when using PrefixFactory to provide a non-static Prefix method (Mono)

[manjaroman2]

I want GUI_ItemManager_Stash__Init_Prefix to be non-static so I can reference the _controller object in my class.

If i set GUI_ItemManager_Stash__Init_Prefix to be static, everything works fine.

public void addHarmonyHooks()
{
    MoreQOD.Instance.HarmonyInstance.Patch(
        typeof(GUI_ItemManager_Stash).GetMethod(nameof(GUI_ItemManager_Stash.Init), AccessTools.all, null,
            new[] { typeof(Profile) }, null),
        new HarmonyMethod(typeof(StashSort).GetMethod(nameof(PrefixFactory), AccessTools.all)));
}

private static MethodInfo PrefixFactory(MethodBase original)
{
    return typeof(StashSort).GetMethod(nameof(GUI_ItemManager_Stash__Init_Prefix), AccessTools.all);
}

private void GUI_ItemManager_Stash__Init_Prefix(Profile profile, ItemController_Stash ____controller)
{
    
    MelonLogger.Msg("GUI_ItemManager_Stash__Init_Prefix");
    MoreQOD.Instance.StashSort.controller = ____controller; 
}
