wait until something while checking for something else

Question

 private IEnumerator WaitForShield(float waitTime)
     {
         print("hi1");
         shield.SetActive(true);
         
         if (Input.GetKey(KeyCode.I))
         {
             if (Input.GetKey(KeyCode.S) && NotShielding == false)
             {
                 anim.SetInteger("AnimParameter", 8);
                 shield.SetActive(false);
                 yield return new WaitForSeconds(0.667f);
                 anim.SetInteger("AnimParameter", 7);
                 
             }
         }
         yield return new WaitUntil(() => (!Input.GetKey(KeyCode.I)));
         shield.SetActive(true);
         print("hi2");
         anim.SetInteger("AnimParameter", 7);
         print(anim.GetInteger("AnimParameter"));
         yield return new WaitForSeconds(waitTime);
         print("hi3");
         shield.SetActive(false);
         NotShielding = true;
     }

I need the if (Input.GetKey(KeyCode.I)) to run while the yield return new WaitUntil(() =>(!Input.GetKey(KeyCode.I))); happens Using a while loop where the if is crashes Unity

Delete the yield return new WaitUntil(() => (!Input.GetKey(KeyCode.I)));

And write

while(!Input.GetKey(KeyCode.I)) { yield return null; }
