Minecraft Modpack error message?

About 10 minutes ago I downloaded a new Minecraft Modpack in the Technik-Launcher. The game crashed after 5 minutes despite my good PC without any error message. When I then searched for the crash reports in the technology folder and also opened the file, this error message came out in the editor:

Have you ever tried to reinstall it?

Apparently there are no negative dimensions - did you enter x / y-values somewhere?

I honestly did not enter anything at all. Just started the game as normal and created a new world.

I also downloaded Technic Launcher and I did not have a mod pack at all. Since then I only use the Twitch Launcher for Minecraft Mods

This is actually only the case with me once.
