Game Version

4.14.1

Describe the bug

When launching the game, the game does not load and exits immediately.

Not even a window appears at all on my desktop.

Please note: I am specifically talking about the flatpak version of the game

Steps to Reproduce

1. Load the game page in Discover
2. Press the Launch button (the game needs to be installed beforehand)
3. Wait a couple of seconds
4. Nothing happens

Alternatively, you can also try to launch the game from the command line, where the following error appears:

I have the same issue with 1.14.1 (jar) on my Mac. 1.14.0 works without issues.

Same error on Wayland.

Temporary solution: Start new terminal emulator window and type:

unset WAYLAND_DISPLAY
flatpak run io.github.yairm210.unciv && exit
