You need to save it somewhere. Either in JSON, XML, or using PlayerPrefs (Not really recommended but okay for small games).

For example add a “Save button”, when the player presses it set

PlayerPrefs.SetInt("CurrentLevel", SceneManager.GetSceneByBuildIndex(SceneManager.Scene.buildIndex);

This will save the current build index to a player pref called “CurrentLevel”.
Then on your main menu have a load button, when you press it you do

int level = PlayerPrefs.GetInt("CurrentLevel");
Scenemanager.Loadscene(Scenemanager.GetSceneByIndex(level));

(This is psuedocode idr all these off the top of my head)

For implementing JSON or XML there’s many tutorials on youtube.

SAVE & LOAD SYSTEM in Unity - YouTube - and then just save the variable to your level (as a String or an int, depends on your preference) as show in this video.

Then create a loading screen as followed: How to make a LOADING BAR in Unity - YouTube. Name the scene “Starter” or so.

Set the “Starter” scene as the start scene (Build settings → set “Starter” as scene 0).

Combine both scripts so you get something like that:

    private void Start()
    {

        if (SceneManager.GetActiveScene().name == "Starter")
        {
            PlayerData data = SaveSystem.LoadPlayer();
            if (data != null)
            {
                Player.level = data.player_level;
                Player.health = data.player_health;
             }
             if (Player.level == 1)
            {
                StartCoroutine(Load(1));
            }else
            {
                StartCoroutine(Load(6));
            }

In the If-statment you just check if the e.g. menu should be loaded or the level.
