This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, xcb.
Aborted (core dumped)
I have tried for two days to get the plug in to work
Ubuntu 20.04

I have the same issue when using WSL2.

On the same version of ubuntu (20.04), managed to fix it with

sudo apt-get install libxcb-xinerama0

so looks like a library was missing
unfortunately I'm not skilled enough at this to properly diagnose which component is missing and just tried a bunch of xcb libraries till I got lucky with this one so maybe it works maybe it won't.
