Opening a file in Musescore 4

Hello everyone,

My problem with Musescore 4 is the following ; when I open a Musescore file a first window appears. Calling another file while Musescore is still open launches Musescore again. At the end I've got as many new Musescore launches as files I called. Musescore 3 would have opened thumbnails. Is there an option that I've missed ?
Thank you for reading this post.
