what its mean if i dont have the 2d assets option?
Unfortunately Unity removed all the packages that used to come with Unity like the standard assets and 2D packages. You can still get them on the Asset store here: https://assetstore.unity.com/packages/essentials/asset-packs/standard-assets-32351 and https://assetstore.unity.com/packages/essentials/asset-packs/2d-sprites-pack-73728
