unity uwp activate deactivate app (KernelBase.dll).

When I activate/deactivate the application, I get an error(exception text below),
In the deactivation process, work is in progress:

Unloading 0 unused Assets to reduce memory usage. Loaded Objects now: 5637. Operation took 69.278259 ms.

after which I get a lot of problems, for example, there is no call event OnComplete DOTWeen

Code (CSharp):

1. DOTween.To(() => _spriteBg.color, x => _spriteBg.color = x, new Color(_colorBg.r, _colorBg.g, _colorBg.b, 0), 0.3f).SetEase(Ease.InQuad).OnComplete(onHideComplete);

StartCoroutine after

Code (CSharp):

1. yield return new WaitForSeconds(1.5f); //wait a few seconds
2. ShowToolTip();

is not called ShowToolTip

if you do not deactivate the application, everything is normal (called OnComplete DOTWeen, run ShowToolTip() etc.)

I did not find anything by mistake number.

Code (CSharp):

While I saw only on the download scene (after deactivation activation) the script stops working

Code (CSharp):

1.   public void StartTutorial()
2.     {
3.         Reset();
4.         StartCoroutine("TutorialProcess");
5.     }
6.  
7.     private IEnumerator TutorialProcess()
8.     {
9.         Debug.Log("TutorialProcess called");  is called
10.         yield return new WaitForSeconds(1.5f);
11.         Debug.Log("WaitForSeconds 1.5 TutorialProcess called"); is not called
12.     }

as a result, the scene does not start working. (But if after evoke the TutorialProcess function by pressing the button it works)

But if after pressing the button (call function TutorialProcess) it works. If skip WaitForSeconds then problem with load texture (texture is null).

If you do not cause deactivation on the scene loading, everything is working fine
