Replace line 76 with:

transform.position + transform.forward,

If the bullet is large then it can overlap the player and push the player away when the physics engine tries to untangle the objects. You can increase the distance the bullet spawns away from the player like so:

transform.position + transform.forward * distance,

You could also place the bullets on a layer that doesn’t interact with the player.
