Unity. When installing builded apk on my tablet, game scenes do Not loading, while in the pc unity they are loading

Question

1. video link demonstrating the problem: Shown: problem, settings, code and logic quick screenshots:
2. "Edit - Preferences - External Tools": what i changed here
3. file - Build settings
4. edit - project settings - player - publishing settings
5. edit - project settings - player - other settings (not all)
6. "Levels" button, script location
7. level menu, all the scenes, lvl button's logic and it's code
8. Other links are in the comments of this post becouse stackoverflow won't let me post more than 8 links in the reason of my low reputation. It must be here, unless this site shadow ban my links.

Caution: links at the top are marked with their serial numbers, which i will refer to in the text below.

To successfully build my unity project without any errors which i received earlier i followed guide from link N8. I checked boxes "custom base gradle template" and "custom gradle properties template" in "edit - project settings - player - publishing settings" (screenshot N10). Also i changed name of the "sdk/build-tools" some of it's versions file named "d8.bat" to "dx.bat" both at it's main foulder and "main/lib" foulder (screenshot N9). Also i changed baseProjectTemplate.gradle and gradleTemplate.properties in "project/Assets/Plugins/Android" (screenshot N11 and N12) after their appearance in this foulder after i checked the boxes in "edit - project settings - player - publishing settings" (screenshot N10). I also installed in android studio Android SDK settings ("Android studio - sdk manager (or "file - settings") - Appearance & Behaviour - System Settings - Android SDK") SDK platforms from android 25 to latest android and in SDK tools i installed Android SDK Build-Tools "25, 30, 31, 32 AND the latest version". These are the highlights. You can find the rest of what I did in the link N8, as i followed the instructions completely.

Description of the problem:

The game have a main menu where at the startup the only button "Levels" shows up. At press, main menu swithes to lvl menu where all the level buttons and a "Main menu" button. When one of these lvl buttons are pressed, the logic (screenshot N7) and code below will run (screenshot N7).

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class GoToLvlButton : MonoBehaviour{
    public Object scene;
    public void GoToSceneScene(){
        SceneManager.LoadSceneAsync(scene.name);
    };
};

In pc unity it works perfectly (video at N1) but when i build it (file - build settings - build), share my apk to my device (Huawei MediaPad M5 Lite 10 LTE "BAH2-L09", EMUI - 8.0.0, Android 8.0.0 (Oreo) API - 26), install and run it at this device, the "Levels" and "Main menu" buttons works fine, but when i click to other buttons in lvl menu, it clicks, but nothing happens.

All scenes already added to "file - build settings - Scenes in build" (screenshot N3).

I tried installing absolutely everything in "Android studio - sdk manager (or "file - settings") - Appearance & Behaviour - System Settings - Android SDK", but it didnt helped. I also several times completely reinstalled all unity hub and it's editors. I tried to install almost everything in additional installations in vs installing. I tried to install almost all modules to my 2022.3.4f1 unity engine. I watched a lot of tutorials, guides and even find two similar posts in two different sites (stackoverflow.com and unity.com), but they didn't helped me too. Tried to clear cache of my project. I tried to install other unity editor versions. I tried to change Minimum API Level and Target API Level to Android 8.0 'Oreo' (API level 26) (becouse it is my device android version) in "edit - project settings - player - other settings" (screenshot N5) but apk build fails no matter what i do.

I expected that when i run my game in my android device it will load scenes, as it do in pc, but it doesn't. My thoughts that problem in the script itself. I really need to run this game properly in my tablet, even if i need to recode all scripts. Thanks for reading.
