Additional context
I will attach the log here:

Seens like the code doesn't check for null
Also wynntils has a custom gui

More context: mod works if wynntils custom loading screen is disabled
Seems like the custom loading screen doesn't have the "exit buttons" so the game just crashes

if i understand this correcly, checking if the button is "null" on the loading screen would fix it
