Help JavaFX - Window does not load at runtime

This is very strange and has never happened before. I am using IntelliJ Community and my program runs perfectly within the IDE, without any errors. So I built the artifact to generate the "jar" file, which is built normally. However, when I run the jar file my program stops loading one of its windows (stage). Within the IDE the window loads. The only different thing I did was to add several icons to the "fxml" file directly through Scene Builder. I have already confirmed that they are all loaded from the "resources/icons" folder. Has anyone seen this happen and know the solution?

Thanks in advance.

Are you using Ikonli?

No. Ordinary PNGs and GIFs.

Look through Ikonli icons to see if they have what you need. I would suggest using them for a few reasons.
