How to make Reloading animation play ONCE

hey guys I am making an FPS game and i reached the level where i make the reloading animations So, I have a boolean and whenever this boolean comes true my reloading animation and sound takes place. Unfortunately I have made a mistake on my scripting so that boolean never goes false as a result my animation never stops playing and i can't continue playing. I have tried to set the wrapMode to ONCE but nothing happends it continues playing like loop. I also tried to make the wrapMode.Once through scripting but also NOTHING happends my animation never stops playing. I have posted my script, let me know if I have skipped any information you may need to troubleshoot my problem.

Here is my script:

 public int currentClip = 6;
 public int currentExtraAmmo = 12;
 public int maxExtraAmmo = 24;
 public int clipSize = 6;
 public bool reloading;
 
 //Animations
     public void AnimationController()
     {
         //JUMP ANIMATIONS
         if(wasStanding && !CharCont.isGrounded)
         {
             wasStanding = false;
             WalkAnimationHolder.animation.Play("Jump");
         }
         else if (!wasStanding && CharCont.isGrounded)
         {
             wasStanding = true;
             WalkAnimationHolder.animation.Play("JumpLanding");
         }
         //RUNNING ANIMATIONS
         if(walkingstate == WalkingState.Running)
         {
             WalkAnimationHolder.animation["Run"].speed = VelocityMagnitude / RunSpeed * 1.2f;
             WalkAnimationHolder.animation.CrossFade("Run", 0.2f);
         }
         //WALKING ANIMATION
         else if (walkingstate == WalkingState.Walking && !reloading)
         {
             WalkAnimationHolder.animation["Walk"].speed = VelocityMagnitude / WalkSpeed * 1.2f;
             WalkAnimationHolder.animation.CrossFade("Walk", 0.2f);
         }
         //RELOADING ANIMATION WHILE WALKING
     else if (walkingstate == WalkingState.Walking && reloading == true)
         {
         WalkAnimationHolder.animation["Reload"].wrapMode = WrapMode.Once;
             WalkAnimationHolder.animation.CrossFade("Reload");
         }
         //RELOADING ANIMATION WHILE STAYING PUT
         else if (walkingstate == WalkingState.Idle && reloading == true)
         {
             WalkAnimationHolder.animation["Reload"].wrapMode = WrapMode.Once;
             WalkAnimationHolder.animation.CrossFade("Reload");
         }
         //IDLE ANIMATION
         else
         {
             WalkAnimationHolder.animation.CrossFade("Idle", 0.2f);
         }
     }
