Unable to launch with failure to initialize QT platform plugin error on Linux Mint 21.2.

[cogwheeloftime]

Describe the bug
Trying to launch the linux-ub22 app image results in failure. Nothing happens if launched through the desktop and trying to launch through the terminal prints an error. I've tried multiple solutions to get around what is described in the error log to see if something was wrong with my system but to no success.

To Reproduce
Steps to reproduce the behavior:

1. If nothing is wrong with my system, launching the app image by normal means on Ubuntu 22.04 (or a distro based on it in my case) results in failure.

Expected behavior
The app launches as normal like the previous version.

See this #82 (reply in thread)
You need to install libxcb-cursor0 if you're using xorg. In wayland you would not have this issue.

Thanks it worked. Sorry I failed to notice this issue was already resolved.

@cogwheeloftime No problem! It was solved in the discussion of release, so it was probably easy to miss.
