Hello good day everyone I've been trying to add a textfield but I am getting an error after another

I created the project, tested it using desktop,html, androidstudio, making use of Shaperenderer, another using an image other than badlogic.jpg and ScreenAdapter and they worked fine... I did all this tests before trying to create a TextField with libgdx, for some reason when testing I realize my core folder doesn't have an assests folder and the "core/assests" folder is at desktop\build\resources\main and it works properly but I am not sure if this could be a problem, as mentioned before I can use images from desktop, android and html if a place them there

Ok so now to the explanation:

This is the code in the class

public class SelectImages extends ScreenAdapter implements InputProcessor{
    
    GameClass game;
    
    TextureAtlas atlasFile = new TextureAtlas(Gdx.files.internal("uiskin.atlas.txt"));
    Skin uiSkin = new Skin(Gdx.files.internal("uiskin3.json"));
    
    Table table = new Table();
    
    

    public SelectImages(GameClass game) {
        this.game = game;
        uiSkin.addRegions(atlasFile);
        TextField txtFieldNum = new TextField("", uiSkin);
        txtFieldNum.setPosition(24,73);
        txtFieldNum.setSize(88, 14);
        table.add(txtFieldNum);
        
    }

I tried this LibGDX - Error reading file: uiskin.json removing com.badlogic.gdx.scenes.scene2d.ui.TextTooltip$TextTooltipStyle:

I got the json file from a github website it was as BitmapFont, Color.... Changed manually to com.badlogic.gdx.graphics.g2d.BitmapFont,com.badlogic.gdx.graphics.Color...

Also created one using the same code.. just open a txt and saved as .json

The whole Json file looks like:

{
com.badlogic.gdx.graphics.g2d.BitmapFont: { default-font: { file: default.fnt.txt } },
com.badlogic.gdx.graphics.Color: {
    green: { a: 1, b: 0, g: 1, r: 0 },

    }
},
}

This is the default.fnt inside my uiskin3.json file the name goes asdefault.fnt.txt otherwise it will not be found

  info face="Droid Sans" size=17 bold=0 italic=0 charset="" unicode=0 stretchH=100 smooth=1 aa=1 padding=0,0,0,0 spacing=1,1

And the uiskin.png file is also the

I got this error

Because of that name: white I procedeed to check the json file, changed white to red

com.badlogic.gdx.scenes.scene2d.ui.Skin$TintedDrawable: {
    dialogDim: { name: white, color: { r: 0, g: 0, b: 0, a: 0.45 } },
},

to

com.badlogic.gdx.scenes.scene2d.ui.Skin$TintedDrawable: {
    dialogDim: { name: red, color: { r: 0, g: 0, b: 0, a: 0.45 } },
},

Mainly to see if the white will change to red and it did, I tried changed rgba values but got the same, so I deleted it, to see the changes

I removed com.badlogic.gdx.scenes.scene2d.ui.Button$ButtonStyle the error jumped to com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle and so on, but I dont know the reason

This is inside my atlas file but I don't know if I should use it and how

......// tree-plus rotate: false xy: 155, 35 size: 14, 14 orig: 14, 14 offset: 0, 0 index: -1 white rotate: false xy: 129, 31 size: 3, 3 orig: 3, 3 offset: 0, 0 index: -1

GameClass extends game and it is use to setScreen(new SelectImages(this));
