[Solved] Could not find the Qt platform plugin "wayland" in ""

obligatory necessary "hi" to make my question harder to read, you are welcome  (:

i am trying to run PulseView nightly using wayland but i get this error

$ ./pulseview-NIGHTLY-x86_64-debug.AppImage 
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.

zsh: IOT instruction (core dumped)  ./pulseview-NIGHTLY-x86_64-debug.AppImage

i do have QT_QPA_PLATFORM=wayland set. Just in case i tried setting it to xcb to see and;

 
$ ./pulseview-NIGHTLY-x86_64-debug.AppImage
ASSERT: "!isEmpty()" in file /opt/qt512/include/QtCore/qlist.h, line 347
zsh: IOT instruction (core dumped)  ./pulseview-NIGHTLY-x86_64-debug.AppImage

i can run the application in CLI mode but im not about to use a 24 channel logic analyzer through CLI, however funny that sounds (:

In case its important i am using KDE, i installed both qtwayland5 and qtwayland6. from the bit i read online it sounded like its an issue with the application itself though id assume xcb would work in that case. the application is open sauce  so i don't mind editing it a little if its all that is needed.
thank you for you help in advance

edit: solution

installing the git version which installed the missing dependencies fixed it
so the missing dependencies was one or multiple of these:
- qt5-base
- qt5-svg
- qt5-tools

i will try this, though i specifically need nightly, as the stable version dosen't support my extremely very fancy and cool logic analyzer (a rpi pico (: )

Seems that i was lacking a dependency as now the nightly version does launch, thanks
can i easily undo what installing it did so i can figure out which specific package it was?
