Starting from version 1.4.6, only files on the desktop can be selected.

I also noticed that the file open dialog is a bit sparse, however my Windows has a My Computer icon on Desktop which allows me to reach every drive in the file open dialog.
As a workaround you can enable `use alternative file dialog" in preferences section "other".

Edit: I see two problems:

1. the side bar which has a large button to go to My Computer has been disabled because of can't not open folder. sum.wat.shell.Win32ShellFolder2.getIshellFolder()  #1709
2. the "Search in" dropdown box only shows "Desktop" because putClientProperty("FileChooser.useShellFolder", Boolean.FALSE); disables it (again because of can't not open folder. sum.wat.shell.Win32ShellFolder2.getIshellFolder()  #1709).

Well, I am also have 'My computer' in desktop view in open dialog, but I don't have it on my desktop, so it is really weird how it added and why it may not be added 🤣
Also, I do my attempts for fixing #1709 without a way to reproduce that issue, so these changes may not be really needed.
And, to be honest, I don't know what to do here. I can't reproduce any of these issues, so fixing them became nearly impossible. I hope someone else can help here, I will keep this issue open for some time.
