^C

qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: xcb.

I'd rather call this a missing feature than a bug though.
QGuiApplicationPrivate::platform_integration = QPlatformIntegrationFactory::create(name, arguments, argc, argv, platformPluginPath);
VS2019 same here with NULL value because not found env QT_QPA_PLATFORM_PLUGIN_PATH, does anyone fix this?
[UPDATE] Maybe solution is here https://github.com/nextcloud/desktop/issues/235#issuecomment-387850103
Bug is still reproducible on Arch Linux, KDE Plasma Wayland, Nextcloud Client 3.11.1. It reproduces as starting under XWayland with the warning message:
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
If QT_QPA_PLATFORM=wayland is used to forcibly start it under Wayland, the following is produced:
$ QT_QPA_PLATFORM=wayland ./Nextcloud-3.11.1-x86_64.AppImage
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""

I noticed this because I rely on fractional scaling for a good desktop experience, which does not function correctly under XWayland.
Years and it still does not work well in wayland :( So also confirming again, same error persists.
