On both Linux systems I've installed QT6 on, my executables crash with qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. On both machines installing libxcb-cursor-dev and libxcb-cursor0 was the answer. These packages should be installed by the Qt installer as dependencies to prevent this issue from recurring.
