The key part of this log is

your vanilla jar may be corrupt.

This means that when your launcher (Curseforge?) tried to download vanilla Minecraft it didn't work.

If you are using Curseforge you should be able to fix this by:

1. Close Curseforge
2. Delete the Curseforge\Minecraft\Install folder. Usually the Curseforge folder is in your Documents, but you may have chosen to put it somewhere else when you installed it originally
3. Restart Curseforge and when prompted reinstall Minecraft
4. Attempt to launch the pack again.
