Exception in thread "JavaFX Application Thread" on tooltip hover over buttons

[supremecmdr]

I am running the game on a Linux Debian 12 with Oracle Java 1.8 which is in it own folder inside the game.
The game loads properly, no problem on the first screen, but when loading any game, once inside the world, trying to hover over any button as the tooltip pops up the errors keep filling the terminal console and error.log as the mouse moves. Also some buttons like Q and E page change do not work with the mouse at all.
I am able to play fully with keyboard and what little else there is still works with the mouse thankfully.

Running the game as "java/bin/java -jar LilithsThrone_0_4_10_7.jar" from within the game folder in the terminal,

terminal console output:
