So i just installed the recommended version of 1.15.2 forge because i want to use world edit. I launch the game in 1.15, quit then launch the forge installer an then the game. it gets through loading and then crashes as the main window starts to open.  I checked the mod folder and it is empty, so i had no idea what to do.

 

here is the crash log:
