Wixel Utility crashing

I am trying to run the wixel config utility but it always crashes on my Ubuntu laptop, with the error message: QPixmap: Must construct a QApplication before a QPaintDevice. Aborted (core dumped). My distro is the Ubuntu 22.04.4 LTS. This is what I get when I try to install the packages necessary:

Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
libusb-1.0-0-dev is already the newest version (2:1.0.25-1ubuntu2).
libqtgui4 is already the newest version (5:4.8.7+dfsg-20ubuntu2~jammy2).
The following packages were automatically installed and are no longer required:
libgsoap-2.8.117 liblzf1 libqt5help5 libqt5sql5 libqt5sql5-sqlite libqt5xml5.

Can someone help me with this? I used the same utility from the user guide.

Hello.

I was able to reproduce the problem, and it seems to be an issue with Qt 4 on Ubuntu 22.04, which is not officially supported by Ubuntu. I made a new release of the Wixel software that uses Qt 5, so please try that. You can download it from the Wixel user’s guide or the link below:

Please let me know if you have any further questions.

Hi David,
Thank you for checking on the problem! I was able to get the utility working. Thank you for the timely response and the release of the utility!

I am getting a warning: libpng warning: iCCP: known incorrect sRGB profile.

I hope it isn’t something to be concerned about.
