Forge profile shows up successfully in Minecraft launcher. When I click Play, it shows a white console-like window titled FML Early Loading Process for a moment before crashing with a generic "a problem occurred" message. The last message on the FML Early Loading appears to be "Launching Minecraft" or similar (it disappears quickly).
Minecraft vanilla 1.14.4 launches fine. I haven't downloaded any mods through Forge, just installed Forge itself via the jar installer. Tried deleting my config folder, no luck.
