VSCode can't find JavaFX or testNG packages, but the program works

As stated in the title, when I run my program it compiles and passes all tests, but there is still a red underline with the import packages. I have reinstalled VSCode and the extension pack for Java. I am running on Kernel: 5.18.0-2-rt11-MANJARO. I have also attached my settings.json file and the source file for my program. Please let me know if you have any suggestions on how to fix this issue.
