Rigidbody won't awake

Hello,

I'm working on a project where I launch a ball with an AddForce, everything works well there.

Here is the script for that part :

 void ThrowEntity()
     {
         GM.loadingRing.Stop(true, ParticleSystemStopBehavior.StopEmittingAndClear);
         GM.rebondMax = (int)GM.powerRay / GM.rebondTimerDiviser;
         GM.timerMax = (int)GM.powerRay / GM.rebondTimerDiviser;
         if (GM.rebondMax < 1 || GM.timerMax < 1)
         {
             GM.rebondMax = GM.rebondMin;
             GM.timerMax = GM.timerMin;
         }
 
         GM.rebondActual = GM.rebondMax;
         GM.timerActual = GM.timerMax;
 
         // Si on possède l'entité et qu'on relache le clic gauche, l'entité ne dépend plus du personnage et est propulsée vers l'endroit où l'on regarde à une force dépendant du temps d'appui du clic gauche
         Ray rayon = Camera.main.ScreenPointToRay(Input.mousePosition);
         RaycastHit hitInfo;
         if (Physics.Raycast(rayon, out hitInfo))
         {
             GM.carrying = false;
             GM.entity.transform.parent = null;
             GM.entity.GetComponent<Rigidbody>().isKinematic = false;
             GM.entity.GetComponent<Rigidbody>().AddForce(rayon.direction * GM.powerRay);
             GM.trail.Play();
         }
 
         // On définit également la durée de vie de la trail en fonction de cette force
         GM.trail_lifetime = GM.trailLifetimeMax * GM.powerRay / GM.powerThrowEntityMax;
         GM.powerRay = 0;
     }

The problem comes with a new mechanics I just added : - I slow mo the game and when I release the mouse click it change the direction by a new addForce. Here it works again. There is the code :

     void SlowMotion()
     {
         if (Input.GetMouseButton(0)) 
         {
             Ray rayon = Camera.main.ScreenPointToRay(Input.mousePosition);
             RaycastHit hitInfo;
             if (Physics.Raycast(rayon, out hitInfo))
             {
                 GM.entity.GetComponent<Rigidbody>().AddForce(rayon.direction * GM.ForceSlowMo, ForceMode.Impulse);
             }
                 
         }
         Time.timeScale = GM.slowMoTimeScale;
         Time.fixedDeltaTime = Time.timeScale * .02f; 
 
     }

The problem comes after. When I pick up the ball after using the slow motion, my rigidbody goes to sleep, so if I want to launch it again the addforce just doesn't work because of that. And the problem is, i can't wake up this rigidbody for an unknown reason.

I've tried : - WakeUp() : in update, at the start of the stack (to determine the force) and right before the launch. - Tweaking the project settings and the treshold for sleeping rigidbody by putting it at 0 - doing a "entity.transform.position = entity.transform.position"

And noone of these solutions i've found on the net is working, i'm starting to being desperate.

Greetings and thanks for your help, also sorry for bad english.
