I believe I figured out the main issue. For some reason, the directories under "res" are omitted in the final JAR. So when it tries to get them, it first catches an exception for when it tries to load the icon for the system tray, then if you patch that out it causes a NullPointerException that it doesn't catch when trying to load main.css. As for you, @Suleman-Elahi I believe you just don't have JFX installed.
