I figured out the source of my problem. A corrupted ~/.config/QtProject.conf file was the problem, and deleting it fixed it!

I had to so some searching...all of my other qt apps seem to use QT5 (and don't have this problem). I found and installed another one that use qt6 and sure enough it has the same file dialog problems. So that explains it. But you said yours uses qt6 and works fine... Both of my apps with this problem were built with QT 6.3.0...I wonder if that is the problem.
I've been using X11 the whole time.
When you say "work fine" do you mean you can do the things that I've described no working? Sorting by column headings (like by modified date), resizing columns, and editing the file path? That's what I really care about. If it used dolphin, I'd expect those things to work, but the important thing to me is that functionality. FWIW, here is what it looks like for me:
I would think "Open it directly" either means by the open file dialog, or by clicking on the file from the desktop environment. I tried this with a flac file that I renamed to the name quoted and I had no problem opening and playing it by any of those ways or by command line. That was with qmmp 2.1.1 using KDE Plasma, on a BTRFS partition.
My system file manager is Dolphin (desktop is Plasma). The file dialog qmmp is giving me does not look like Dolphin. I am not positive of this, but I think previously, before I had this issue (that is when I could sort the dialog by columns, edit the path, etc) it did look like Dolphin.
Also, from the about dialog: Version: 2.1.1 Using Qt 6.3.1 (compiled with Qt 6.3.0) Is the behavior I'm seeing specific to my distro? Should file an issue with openSuse?
