I am new to javafx.Currently I am developing a miniproject.I am designing it's UI in scene builder-18.0.0.
I have added fontawesomefx jar file to reference library.
When I use fontawesomefx icons to my project, it's shows the following Exception.If I remove the icons, the program runs fine.
Result

I also tried with the following vmArgs

I also visited this post and used fontawesomfx 8.4.but it didn't work.It shows the same exception.
Currently I am using java 18(jdk-18.0.2) and javafx-sdk-18.0.2 and SceneBuilder-18.0.0 and fontawesomefx 8.9 jar.I use visual studio code.I am not using any built tools for my project.
NOTE:If I run the code without any fontawesomefx icons, my code works fine.
I have been searching the solution for this problem for an entire day.Please explain me what is the problem and how to solve it.I want to use fontawesomeicons in my project.How to do it?
Thank you
