Version 12.1 installed from Snap Store not launching (Ubuntu 22.04)

[fohrloop]

Installed from Snap Store the engauge-digitizer version 12.1 on Ubuntu 22.04. The program wont start if starting from launcher (no errors either). When starting from command line, I get:

niko@niko-ubuntu-home:~$ engauge-digitizer
This application failed to start because it could not find or load the Qt platform plugin "wayland-egl".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

When installing engauge-digitizer with apt install, version 12.1 gets installed, which works. It gives this warning on startup:

niko@niko-ubuntu-home:~$ engauge
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
