I just switched from Ubuntu 20.04 distro back to Windows with integrated WSL 2, and I am having trouble running my JavaFX project.
I get the following error stacktrace around launch(args) inside main method :

Things I have tried
I looked at almost every post on SO regarding this issue with no success.
sudo apt install libgtk-3-0
was not a fix since I had already this installed.
I also tried to delete openjfx and reinstall it from a different mirror, with no success. Currently the package I have, I have installed it with
sudo apt install openjfx
Does anyone have an idea of what may be going on here ?
