Modpack that doesn't even launch the game

Hi, I recently downloaded the MineColonies modpack with Forge, when I start it, the launcher is opening but then, when I try to play, it crashes instantly and don't even appear in latest log of the game, so I assume the problem comes from the launcher.

I've already contacted the modpack devs' but couldn't help me.

 

Here is the link to a git of the crash report text
