Help my game wont launch

[SpaghettiBoi]

I think I've tried just about everything I've seen on the internet, but my game still refuses to launch, I was playing a game as "Svipjod" when suddenly my game crashed and now it refuses to open with out immediately closing itself, all i see when i launch is the white window of the launcher before it closes itself. I've tried changing compatibility settings, validating my steam files, updated all of my windows and Nvidia drivers, and even full resetting my PC nothing seems to work! I really need help cause I'm losing my mind i just want to play Crusader Kings 2.

Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK2
- manually delete both the Steam/SteamApps/common/CK2 AND Documents/Paradox/CK2 folders
- re-install game in Steam, run a Steam Verify when done.
- add ck2game.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam CK2 or Documents CK2 locations, before installing again.

Also if you have installed RivaTuner, RadeonPro, or a gaming VPN app called Evolve, or the MSI Gaming App, or Duet, disable it as it clashes with this game.


IF NEITHER OF THOSE HELP:
DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please attach your Documents/Paradox/CK2/settings.txt
From your Documents/Paradox/CK2/logs/ folder, attach system.log .

OK so in previous tries I've realized that I've never fully deleted my save files just dragged them out, i fully deleted them this time and the launcher seems to have opened correctly, and i played a test game, but as soon as i dragged my save files back in the launcher wont open so i have to assume that one of my favorite save files is corrupted. thank you Andrew for your help, i had not realized that the save games could crash my launcher!
