Please explain your issue is in as much detail as possible.
I am trying to start a new game after the 3.8 Gemini update. I can't continue past the empire creation screen. When trying to make a Dictatorship government I get an error under the "ruler traits" tab. The error is attached in the screenshot, stating "Ruler has a Class that is not allowed for the selected Government Authority". I have disabled all mods and I am receiving the same error. Please see the attached image. I have tried several different Races and Government types but it will not let me make a new game. The game will not let my leader be a General, Admiral, Governor, or Scientist.

EDIT: Added second screenshot where I have all mods disabled and all DLC enabled. Tried to make a Machine Gestalt empire. Was enough to replicate the bug. Added a Reddit sceenshot of a forum where a dozen people are having the exact same issue as I am. They all play with different mods, or no mods at all. The issue started for everyone the day of the 3.8 roll out after the first update was pushed out via Steam. I know I have gone back and validated all of my game files through Steam just to be sure and none of the files seem to need replaced. The only thing left would be to delete the game and re-install from scratch. But if that's the case then why are several people having the exact same issue?

Steps to reproduce the issue.
I purchased the new DLC. Waited two days to let you guys patch the patches. Logged in to make a new game because I knew my old save would be toast. Tried to make a new game and ran into this error on the first run. 100% happens every time I try and make a new game. I can not get past the new game screen even with all of my mods turned off. I even tried turning off the new DLC.

Hello!

Thank you for the report!

If the issue persists after disabling all the mods and going through Steam's file verification please try a clean reinstall, by uninstalling the game,
deleting the C:\Program Files (x86)\Steam\steamapps\common\Stellaris (for windows) folder and reinstalling the game.

Had to delete game and do a clean re-install. The 3.8 update borked something to the game files. But now the game works even with all the mods turned back on.

Ok found the culprit. Just an update for anyone else who may experience this same issue. Somehow when I turned off all the mods a bit of code from z Expanded Traits, Civics, Pops, and More 3.7 had made it's way into the main game file. This did not play well at all with the 3.8 update. Not sure how I managed this but glad I fond it in the end for my own sanity.
