I've had this problem for the past two days. I've tried using three different versions of forge for 1.14.4 from 28.0.47 - 28.049.Yet none seem to work. Every time it crashes with the message, Game crashed An unexpected issue occurred and the game has crashed. We’re sorry for the inconvenience. I've used older versions like 1.12.2-14.23.5.2768 and 1.8.9-11.15.1.1722 and they work perfectly. I can provide the crash log. But I was wondering If i need to include the debug from the game output.
