Hi I can't run Forge and any help is much appreciated. Successfully installed forge installer forge-1.14.4-28.1.106-installer.jar Started the Minecraft Launcher 2.1.9618 Started forge-1.14.4-28.1.106 The game window comes up for a few seconds (1 or 2 sec) showing the white screen where you can read information about the program like Heap Memory ... Then it collapses already and I read the message in the launcher: An unexpected issue occured and the game has crashed.
