Swing(jFrame) can not initialize

Since switching to Wayland, I stopped using the SDK due to some issues I encountered, so I’m not very familiar with the project structure it generates. It might sound strange, but have you tried creating a blank project and configuring it (either with Gradle or another) in the simplest way possible in another IDE? Or, use the initializer that has jme (here) to create the project. As @pspeed said, it’s possible that SDK is passing some parameter that prevents AWT from starting. > To me that means the SDK is passing a parameter or something that’s causing issues.
