This is a regression in QtWayland. If this is still reproducible with Qt 5.12.0, I suggest to report it to Qt developers via https://bugreports.qt.io/ The drop-down is supposed to 'eat' bother Enter and Esc keys, so that applications don't receive these keys unintentionally.
I can't reproduce such crash here under Wayland. Operating System: Arch Linux KDE Plasma Version: 5.15.1 KDE Frameworks Version: 5.55.0 Qt Version: 5.12.1
Me neither. I guess it eventually got fixed upstream.
