Issue importing CSV file to QGIS and use it as shapefile

I’m trying to import a CSV file to work on a point shapefile in QGIS 3.14

In Excel, my CSV is as follow : ID, X&Y coordinates, and another field (H)

I then go to Layer – Add a Layer – Add a text-delimited layer and import the CSV with the following parameters :

But upon importing, my CSV does not show as a shapefile, it shows with the csv icon (the TEST layer) and I cannot do anything with it (I cannot display the points, or the label)…
If think my QGIS configuration might have changed….
How can I correctly import the CSV file ?
