Tekxit doesn't work!

Hi. I have a problem with the Tekxit modpack. When i try to start my server, it take so long in the Starting process. When it starts, after 5/6 seconds it crash.
Why? The versions are the same, the modpack too. The console doesn't say nothing about this problem. I don't know what to do and is pretty urgent

Thanks (I'm sorry for the bad English)

Here it is. My UserName in Aternos Board is GoldenPixel_ and for the server i use an other Account (RedFire69). If RedFire69 doesn't exist, i d

I just created a new normal World, and always, before i start a different type of ModPack, i refresh the world (i create a new one)

I generated a new Default world and reinstalled the Modpack. The problem is the same: I wait the queue, the loading and starting process and when is open, after 5 seconds it stops.

This time, the Log changed:
