On Debian Sid, installing the following packages solved the issue for me:
apt install qml-module-qtquick-controls2 qml-module-qtgraphicaleffects qml-module-qtqml qml-module-qtquick-layouts qml-module-qtqml-models2.

If you stop the process and start nextcloud-desktop with the --logdebug and --logfile parameters, do you see anything in the logs or as output of the process?

It's the same for me running GNOME on openSUSE 15.2 (x86 though...). In the output of

nextcloud --logdebug --logfile nextcloud.log

I found the following lines:

2020-09-11 19:41:42:592 [ warning default ]: QQmlApplicationEngine failed to load component 2020-09-11 19:41:42:592 [ warning default ]: qrc:/qml/src/gui/tray/Window.qml:7 module "QtGraphicalEffects" is not installed qrc:/qml/src/gui/tray/Window.qml:5 module "QtQuick.Controls" is not installed qrc:/qml/src/gui/tray/Window.qml:7 module "QtGraphicalEffects" is not installed qrc:/qml/src/gui/tray/Window.qml:5 module "QtQuick.Controls" is not installed

Missing Qt components might explain the missing window. For me this merely affects the main window. I can still access the settings window after installing a tray icon extension for GNOME.

installing the missing dependencies libqt5-qtgraphicaleffects and libqt5-quickcontrols2 solved the issue for me. Still, any window is merely available installing a tray icon extension.

@jonascant is it a dependency issue for you as well?

If that's it then it's not arch specific like the title indicates and that would be a packaging issue. In the case of openSUSE it would need to be reported there. In the case of Debian, @ivaradi could you fix this in our ppa please?

I can't test on that machine ATM. But i did install on a x86_64 machine (also debian testing) with the same problem. So i think it is not an arch thing. I got it working with a flatpak. However the new blue window that links to the cloud website does not seem to respect the GNOME design-guidelines. It is not movable and without a tray icon, i can't open it after i closed it.. Would it be possible to create two separate packages? The settings window as a standalone package for people who just want to synchronize and create another package with the widget window, where the settings app is a dependency? For now i am forced to pin the app down to 2.5 which works nicely.

OK, so that kind of confirm the missing dependency issue on debian packages. @ivaradi could you look into this please?

This is a separate issue, we got that design decision discussed in another ticket.

I have added the qml-module-qtqml package as a dependency to the Debian Testing package (the other ones listed here: https://github.com/nextcloud/desktop/issues/2390#issuecomment-691625475 were already there). The 3.0.1 package has been rebuilt with it, so please, test it and let me know your results.

The issue appears to be resolved with latest nextcloud-desktop=3.0.1-3 on Debian Unstable.

m1435 on 28 Sep 2020

The issue still persists for me on Debian Testing, probably because nextcloud-desktop 3.0.1-3 from the Debian repos (and the version available in the official PPA) is packaged with all the packages mentioned by @m1435 except qml-module-qtqml. Installing it solves the issue.
