Package Manager doesn't download properly when downloading a version of Unity

I’ve started with Unity just today and I’m using an Udemy course recommended by my friend. So I am making my first project and whenever I make the project and it automatically opens it and then it says that file’s in the package manager are missing and it says that every time I redownload a version and it never downloads all the files.

If it helps I use macos

Do you have any errors in your console, by chance?
