I have created a custom modpack, to which I have done this several times with no issue. Only, this time I launch the pack and it opens the minecraft launcher, I press play and it loads and closes, but no "Mojang" window comes up. However, in task manager it shows it as running but I cant expand it. The pack has 135 mods, of which I have created and ran modpacks with more than this. Any thoughts as to the issue? Attached below is a list of the mods and the forge version.
