main screen -> Play -> IMPORT
main screen -> Play -> EXPORT SAVEGAME
As soon as I click either button, the game hangs a few seconds, then crashes. Player.log shows a stack trace. It mentions GTKOpenPanel and XDefaultRootWindow, among other things. I'm running in KDE Plasma, Wayland, Vulkan. (The SHOW FOLDER button works fine -- opens Dolphin.)
The troubleshooting guide mentions "Exporting a save to anything but the default path & filename seems to crash". But this happens before choosing any path or filename.
