Description of Problem:

Hi.

I'm preparing a modpack for a youtube series with 28 more youtubers, but when i load it from the Technic Laucher, it goes to white screen after the Mojang logo.

I have made a lot of Minecraft with mods series before, but i never made a custom modpack!

I'll give a shoutout to the person who finds the bug

Here's the Technic Platform link:
