Loading game data crashes on android

My game works in editor but crashes on Android. It appears to break when trying to load from a save file. Essentially, I save a bunch of dictionary values into Lists and then set the values of the dictionaries to the saved list values on load.

 using UnityEngine;
 using UnityEngine.SceneManagement;

 using System.Runtime.Serialization.Formatters.Binary;

     public static Dictionary<string, double> multiplierUpgradePrices = new Dictionary<string, double>(); //Key is the clicker, value is the price of upgrading
     public static Dictionary<string, double> clickerPrices = new Dictionary<string, double> (); //Key is the clicker, value is the price to unlock the clicker
     public static Dictionary<string,Boolean> unlockedClickers = new Dictionary<string,Boolean>(); //Key is the clicker, value is whether or not its unlocked
