Thanks for the suggestions @joekamprad and @judd . I managed to solve it. I have been on Antergos for a good year now and sometimes it seems I have not yet learnt the basics of Linux I should have thought about just launching it from the command line myself. Well, lessons learnt, so a wholehearted thank you!
Starting rapid-photo-downloader from the command line showed an error about the locale in python. I live in Belgium but I prefer English on my computers, so I have a mix of locale settings.
The output of locale gives:
It turned out however that nl_BE.UTF-8 was commented out in /etc/locale.gen. So I uncommented it and ran locale-gen in the terminal, and that fixed the issue
I am using an up-tp-date Antergos KDE system. I can install Rapid Photo Downloader, and it appears in the KDE menu, but it won’t run. I have tried both the repo version and the AUR version and both have the same problem.
Journalctl -f shows the following lines when I try to launch the program
kwin_x11: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 22098, resource id: 94372310, major code: 18 (ChangeProperty), minor code: 0
kwin_x11: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 24578, resource id: 94372318, major code: 18 (ChangeProperty), minor code: 0

I’ve noticed that starting other programs like Krita also results in these type of messages, but those programs still seems to start normally, even with those messages in the log.
For Rapid Photo Downloader however, these 3 messages are all I get. Nothing happens after that. No window, not even a flicker of a window.
Is anyone else having the same issue? Or can someone perhaps point me in a direction where I can look further?
Thanks in advance!
@BlaiseD Wow thanks! I had a different problem but it turned out it had a similar cause.
After a botched system update I could not get past the lightdm login screen anymore. The screen went black with a cursor, flickered for a moment, and I was thrown back to the login screen.
pacman -Dk revealed problems with kauth so as per your explanation I rm’ed the /var/lib kauth folder, and after a pacman -S kauth --force with a reboot I had my system back.
Million thanks for the solution!
