Shotcut under crostini/chromebook. Cannot import any file for editing

i have a chromebook HP (8 gb ram , i3, 256 gb disk) with chrome os and crostini (debian 11) installed. Everything works like a charm but since i am not satisfied by the lumafusion video editor or even the new google foto editing, i successfully installed shotcut.
i have my video in a folder (of course shared with linux) /mnt/chromeos/Download/videos
but when i try adding files from there to start a new project as soon as i get into the Download folder it doesn’t show any other subfolder/files. So there’s no way to import anything. For what is worth, it happens with openshot also. I don’t know what to do :frowning:
Happy Xmas to you all
