Targeting system error on destroyed target

Question

I have a targeting system that selects the closest target from a list , like so:

 using System.Linq;

         if (Targets.Count>0){
  selectedTarget = Targets.OrderBy(t=>(t.position - transform.position).sqrMagnitude)
                            .FirstOrDefault();}

It works great but it has started to give me the following error whenever i destroy a target and I can't work out why.

MissingReferenceException: The object of type 'Transform' has been destroyed but you are still trying to access it.Your script should either check if it is null or you should not destroy the object.

Good day.

This is because the code is trying to read a variable of the destroyed object.

You need to remove that element from the list when you destroy it, so the code do not try to read that variable (that is null)

Bye!
