Hi,

Just replace 
splitString = record.splitemail__c.split(',');
with
splitString = String.valueOf(record.splitemail__c).split(',');

I hope this helps. Kindly mark solved if it does.

Best Regards
Veenesh

Kindly check if your record has value in the field "record.splitemail__c".

In your class: 
public with sharing class Backup_ExtensionController {
    public Backup__c  bk{get;set;}
    public List<string> splitString {get;set;}
    
    public Backup_ExtensionController(ApexPages.StandardController controller) 
    { 
      controller.addFields(new List<string>{'splitemail__c'});
        Backup__c record = (Backup__c)controller.getRecord();

        splitString = new List<string>();

        if(!String.IsBlank(record.splitemail__c)){
           splitString = String.valueOf(record.splitemail__c).split(',');
           system.debug('----->splitString ' +splitString );
		}
		else
			system.debug('----->splitString is blank' + );
    }
     
}

Hope this helps.
