Crouch and Prone System for FPS game

[solemn sigil]

I'm trying to create a crouch and prone system in my FPS game. I want the player to go from stand -> crouch or prone -> crouch when the player's current height is at the stand or crouch heights. The stand -> crouch works fine and I can toggle between them. The issue comes when I try to go from prone -> crouch and my character just stays prone. I can go from prone -> stand fine but I want to make it so that I can go from prone -> crouch -> stand from pressing the crouch button. I'm using the input system to try and accomplish this. This is everything I have in my script relating to this:

also I would highly suggest you look into using an enum for this to make it less confusing

private enum PlayerState 
{ 
    Stand, 
    Crouch, 
    Prone,
    Sprint
}
private PlayerState stance = PlayerState.Stand;
void Start()
{
    currentSpeed = walkSpeed;
    currentHeight = standingHeight;
    Cursor.lockState = CursorLockMode.Locked;
    Cursor.visible = false;
}
    private void HandlePlayerHeight()
    {
        // Toggle crouch
        if (playerInputHandler.CrouchTriggered)
        {
            if (stance == PlayerState.Stand)
                stance = PlayerState.Crouch;
            else if (stance == PlayerState.Prone)
                stance = PlayerState.Crouch;
            else if (stance == PlayerState.Crouch)
                stance = PlayerState.Stand;
        }

        // Toggle prone
        if (playerInputHandler.ProneTriggered)
        {
            if (stance == PlayerState.Stand || stance == PlayerState.Crouch)
                stance = PlayerState.Prone;
        }

        // Set height based on stance
        switch (stance)
        {
            case PlayerState.Stand:
                currentHeight = standingHeight;
                break;
            case PlayerState.Crouch:
                currentHeight = crouchHeight;
                break;
            case PlayerState.Prone:
                currentHeight = proneHeight;
                break;
        
        }

        characterController.height = Mathf.Lerp(characterController.height, currentHeight, Time.deltaTime * crouchTransitionSpeed);
    }

This is what I have now and it made the issues worse

The player object is half stuck in the ground when testing and crouching or going prone makes him sink through the floor. Also the input for crouching is really inconsistent, like sometimes Ill press it and it crouches but then Ill press it again to stand up and it works but sometimes it also has the chance to go prone instead.

Also going from prone -> crouch pressing the crouch trigger just doesn't work either

where did you read you only change controller height?

of course it goes in the ground

also ofc the rest doesn't make sense thats why its broken

[solemn sigil]

Sorry im not sure what you are referring to

[sage hare]

characterController.height =
did you write any of this code?

[solemn sigil]

I wrote some of it and it didn't work so I plugged it into AI and it gave me this

The switch stance stuff was what it added
