Stack Overflow error on delegate call

This is very puzzling! I'm working on a quest system and have chosen to use c# events. I have a quest giver script placed on a model, I have a quest panel that tells the player about quest and gives them the choice via button to accept the quest or not( yes button and no button). I also have a journal script to keep track of current and completed quests. I set up a delegate and event for OnAcceptQuest. Just as a test, I set up a keypress to add the quest, which worked. Only when I try using the button, it didn't work at all; the quest was getting lost so I found a way around that, I thought. Now I'm getting a Stack Overflow error when I try to add the quest via click on a button image. This post is a little long-winded, but I am trying to give as much info as possible. Now for the code:

Event Manager: public class EventsManager { //Quests public delegate void QuestAddDelegate(QuestClass quest); public static QuestAddDelegate OnAcceptQuestEvent; public static void AcceptQuest(QuestClass quest) {

         if(OnAcceptQuestEvent != null)
         {
             OnAcceptQuestEvent(quest);
         }
     }
 }

Quest Giver: private void OnTriggerEnter() { print("Open panel"); OpenQuestPanel(); }

     private void OnTriggerExit()
     {
         print("Close panel");
         CloseQuestPanel();
     }
 
     private void OnEnable()
     {
         EventsManager.OnAcceptQuestEvent += AddQuest;
     }
 
     private void OnDisable()
     {
         EventsManager.OnAcceptQuestEvent -= AddQuest;
     }
 
     public void OpenQuestPanel()
     {
         if(Quest.questStatus == QuestStatus.Unassigned)
         {
             QuestPanel.SetActive(true);
             PresentQuest();
         }
 
         else if(Quest.questStatus == QuestStatus.InProcess)
         {
             QuestPanel.SetActive(false);
             ProgressRewardPanel.SetActive(true);
             QuestInProgress();
 
         }
         else if (Quest.questStatus == QuestStatus.Complete)
         {
             Rewards();
         }
         
     }
 
     public void CloseQuestPanel()
     {
 
         QuestPanel.SetActive(false);
         
     }
 
     void PresentQuest()
     {
         QuestPanel.SetActive(true);
         IntroText.text = Quest.introText;
         QuestDescText.text = Quest.questDescription;
         RewardText.text = "You will receive " + Quest.reward + " for your trouble.";
     }
 
     //public void OnClickYes()
     //{
         //questAccepted = true;
     //    Debug.Log("Yes, accept the Quest!");
 
     //    AddQuest(Quest);
         //checkquest();
         // Add quest to the active quest list
         // change icon to hourglass
     //}
 
   
     public void OnClick()
     {
         Debug.Log("Yes, accept the Quest!");
         AddQuest(Quest);
     }
 
     public void OnClickNo()
     {
         
         RefusalText.text = Quest.refusalText;
         
     }
 
    
 
 
     void AddQuest(QuestClass quest)
     {
         EventsManager.AcceptQuest(quest);
         Quest.questStatus = QuestStatus.InProcess;
 
     }
 
   
 }
 Journal:
 private void OnEnable()
     {
         EventsManager.OnAcceptQuestEvent += AddQuest;
         EventsManager.OnCancelQuestEvent += RemoveQuest;
     }
 
     private void OnDisable()
     {
         EventsManager.OnAcceptQuestEvent -= AddQuest;
         EventsManager.OnCancelQuestEvent -= RemoveQuest;
     }
 
     void Start()
     {
         
     }
 
    
     void Update()
     {
         
     }
 
     void AddQuest(QuestClass quest)
     {
         CurrentQuestList.Add(quest);
         print(CurrentQuestList.Count);
         ShowCurrentQuests();
     }
 
     void RemoveQuest(QuestClass quest)
     {
         CurrentQuestList.Remove(quest);
         print(CurrentQuestList.Count);
     }

Test script:

  void Update()
     {
         if (Input.GetKeyDown(KeyCode.Q))
         {
             print("Q");
             EventsManager.AcceptQuest(quest);
         }

Thanks in advance!
