Cant show my features in openlayers. Does someone know how to solve this?

I have been struggling with my projections for a few weeks now. At the beginning I could show my features but they appear in jemen (they are supposed to be in Italy). After I realised my coordinates were being inversed, for example my coordinate [41.18702782291,15.450187402143] (which is in Italy) was displaying in [15.450187402143, 41.18702782291] (which is in jemen), I decided to invert the coordinates of the multipolygons of my geometries so that now I have the [15.450187402143, 41.18702782291] format. I don´t know what happened but now I cant see my features shown in the map.

I have an object geojson with my features and this is my code:


var myview = new View({
  center: [15.450187402143, 41.18702782291],
  projection: 'EPSG:4326',
  zoom: 6
})

var mylayer = new TileLayer({
  source: new OSM()
})

var layer = [mylayer]

const map = new Map({
  target: 'map',
  layers: layer,
  view: myview
}); 

const vectorSource = new VectorSource({
  format: new ol.format.GeoJSON(),
  features: (new ol.format.GeoJSON()).readFeatures(geoJson, {dataProjection: 'EPSG:4326',
  featureProjection: map.getView().getProjection()})
  //EPSG:32633 - WGS 84 / UTM zone 33N
  //features: new GeoJSON().readFeatures(geoJson, {dataProjection: 'EPSG:4326', FeatureProjection: map.getView().getProjection()})
});

console.log(geoJson);
console.log(vectorSource.getFormat());
vectorSource.addFeatures((vectorSource.getFormat()).readFeatures(geoJson));
console.log("1");
const vectorLayer = new VectorLayer({
  source: vectorSource
});

map.addLayer(vectorLayer);

const numFeatures = vectorLayer.getSource().getFeatures().length;
console.log("Count right after construction: " + numFeatures);

The final lines show that the features are in the source and it is correctly getting them.
