here’s the code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class SoundManager : MonoBehaviour
{
    [SerializeField] Slider volumeSlider;

    // Start is called before the first frame update
    void Start()
    {
        if (!PlayerPrefs.HasKey("musicVolume"))
        {
            PlayerPrefs.SetFloat("musicVolume", 1);
        }

        else
        {
            Load();
        }
    }

    public void ChangeVolume()
    {
        AudioListener.volume = volumeSlider.value;
        Save();
    }

    public void Load()
    {
        volumeSlider.value = PlayerPrefs.GetFloat("musicVolume");
    }

    public void Save()
    {
        PlayerPrefs.SetFloat("musicVolume", volumeSlider.value);
    }
}

Don’t do stuff like this, scattering and splattering string literals everywhere:

Here’s an example of simple persistent loading/saving values using PlayerPrefs:

Useful for a relatively small number of simple values.

Beyond that…

Sounds like you wrote a bug… and that means… time to start debugging!

By debugging you can find out exactly what your program is doing so you can fix it.

Use the above techniques to get the information you need in order to reason about what the problem is.

You can also use Debug.Log(...); statements to find out if any of your code is even running. Don’t assume it is.

Once you understand what the problem is, you may begin to reason about a solution to the problem.
