Modpack Crashes After Launching

Crash log: https://pastebin.com/mA8F5WBa

RAM Setting: 4 GB

When I click launch on "The World War II pack" it crashes after pre-initializing different mods.

If any more information is required let me know.

That's not a complete log, but my best guess is that you're missing a critical core mod or other mod file, since that's usually what's going on when Java tells you there's no class definition found.

I'd try the Technic Discord, if you can, or wait for someone that knows more about the launcher as it stands.  Or PM the mod pack creator, if you're brave.
