Select home directory dialog can't select a directory
I want to select a new home directory for JDK, as I want to use a newer JDK. However, when selecting NEW -> JDK in the Project SDK settings, a Windows XP style dialog opens up, in which I can only select files and not directories. When I select an arbitrary file in the directory I really want to select, nothing happens.
This is the dialog I get:

This also applies to other projects, I have already invalidated my Caches and I'm sure it has worked once upon a time. This is the result I receive from "About":

IDE should show its own dialog, I can't get the Windows default dialog when following your steps on Windows 10.
Did you override any IDE settings?

And actually I have quite a few settings, see my settings repo:

Note that deleting the .IntelliJidea2019.1 folder fixed the issue - this is not a great solution though. This does not mean, that there's a proper explorer, because there isn't. It just defaults to the newest Java version, after having forgotten that an old version was selected, which works in my case.
