Regarding your issue with the loading screen background, I'm afraid that customization of the game loading screen (the splash screen during startup) is not natively supported by FancyMenu. For that purpose, you should use the Drippy Loading Screen mod, which is specifically designed as an addon for FancyMenu to handle those loading screens.
Since you are experiencing issues with scaling on that screen, I recommend checking the documentation or support resources for Drippy Loading Screen, as that is where you would configure the background behavior for that specific screen.
If this happens on a menu you did customize with FancyMenu and it relates to the GUI scaling, you might want to look into the Auto-Scaling feature. You can enable this by right-clicking the editor background in a layout, forcing a GUI scale, and then enabling Auto-Scaling in that same menu. This is often helpful to ensure elements scale correctly with Minecraft's GUI settings.
If you are encountering a crash or a technical error with the mod itself, please provide your latest.log file and press the "Request Human Help" button so a developer can take a look! 😊
