Trigger System Limit Exception: Apex CPU time limit exceeded

Dear Experts,

I am getting "System Limit Exception: Apex CPU time limit exceeded" on my trigger. Kindly help me to correct the logic. Thank you very much for your quick help!

Trigger 
trigger ContactTrigger on Contact (before insert, after insert, before update, after update) { 
    
    if(Trigger.isBefore && ContactTriggerHandler.runContactTrigger){
        if(Trigger.isInsert || Trigger.isUpdate){
            ContactTriggerHandler.validateAliedRegistrationNumbers(Trigger.new);
            ContactTriggerHandler.validateAClientMDHHSNumbers(Trigger.new);
            ContactTriggerHandler.setContactAccountByCaseIds(Trigger.new);
        }
    }
    if(Trigger.isAfter && ContactTriggerHandler.runContactTrigger){
        
        if(Trigger.isInsert){
            ContactTriggerHandler.getHouseholdAcctsForSharing(Trigger.new, Trigger.newMap);
            ContactTriggerHandler.runContactTrigger = false;
            ContactTriggerHandler.insertSubsidiaryAccounts(Trigger.new);
        }
        if(Trigger.isUpdate){
            ContactTriggerHandler.runContactTrigger = false;
        }

It would be difficult to tell why you see CPU time limit exception.  Debug logs is the best way to narrow down the scenerio and check the issue.

Check below references for check point details.

I agree with Vinay. Logs are best place to find solution. 
I came across such scenario and I was able to use @ future method to perform some updates asynchronously. Let me know if you still need help.

Hi Vinay/Mentee.

I am sorry for the late response!

Here is the stack tree.

I think the issue is with the following highlighted code. Kindly suggest the code to avoid the Apex CPU time limit?
