Whenever I try to start a new game, the first time I try to start it this screen pops up

And if I try again it goes to the loading screen but it won't go past this stage even if I wait for around 10 minutes (which I spent on the Internet, not waiting with the game on screen).

I had 5 mods as of the time of the Dianostics, but none of them were enabled:

Ultimate Custom Faction

Kaizen Rejuvenation Long

+More Trait Points

PlanetTypeEden

I removed the last one, Unlimited Trait Count [Deprecated], but the problem still persists.

What mods do you have  loaded, I was getting this with endless legends pop mod before the developer updated and squashed a bug

HAHA! I'VE SOLVED THE PROBLEM!!!

I've checked the errors and warnings, and in both diagnostics they refer to the factions or mods that I've deleted and removed, all except for "Gameplay   STACK   An exception was raised when executing GameServerState_LaunchGame."

I thought this weird, and upon doing a search of the Endless Space 2 folders, I saw that the .xml files for some of the custom factions and its populations were still in Library/Application Support/Endless Space 2/Custom Factions

After finding what was likely the cause of all my frustration and lost time, I went through that folder and cleansed everthing that shouldn't exist like a fiery-sword-wielding-maniac.

HURRAH!!! I can now start a new game!

Ahem. Any ideas on what caused this?

Nice! Glad it works!

Edit: I can't specifically tell what might've caused it without looking at the faction you have deleted to see why, but just from experience, "An exception was raised when executing GameServerState_LaunchGame" is more of an effect than a cause (aka. something else is causing that to happen, usually broken/incorrect pathing somewhere)

Ultimate Custom Faction hasn't been updated in 2 years, with More Trait points not being updated in 1, so that might be a cause. (Something additional after looking into them, both have comments saying that they are broken).

I've used PlanetTypeEden before, and have never had a problem, same things goes with Kaizen Rejuvenation.

My guess from all of this? You made a faction using something from one of the broken faction mods (probably before it was broken), and when the game tried to load it it had a stroke.

Just some help in case you have problems in the future, I've made a helpful key for reading the error logs
