Hello there,
I solved the problem for me...so read below and check what you need to do and let me know if it worked for you.
After a crash during my game when i tried to start the game the launcher wasnt even appearing anymore.I tried many solutions but nothing was working.
I reinstalled the game 3-4 times nothing...i was keep deleting everything in the folder C:\Program Files (x86)\Steam\steamapps\common\Crusader Kings II to make sure that everything was deleted...nothing...
Eventually i figured out the problem and i fixed it .How? The answer is simple...
I was keep focusing deleting only the C:\Program Files (x86)\Steam\steamapps\common\Crusader Kings II but i was missing the fact that in my documents there was a paradox folder with files inside gfx,logs,mod,dlc signature ,pdx login etc etc....
So what you need to do...is DELETE EVERYTHING INSIDE THIS FOLDER AND REINSTALL THE GAME....
Let me summarize now the steps.
FIRST you UNINSTALL THE GAME....
CHECK THE C:\Program Files (x86)\Steam\steamapps\common\Crusader Kings II .This folder should NOT beTHERE ANYMORE...
THEN CHECK YOUR DOCUMENTS AND FIND THE FOLDER OF PARADOX
C:\Users\(YOUR USERNAME FOR YOUR PC)\Documents\Paradox Interactive\Crusader Kings II
AND DELETE EVERYTHING INSIDE THE FOLDER...
Then perform a clean installation and go check both destinations and you will see for the first destination that the game is installed
(C:\Program Files (x86)\Steam\steamapps\common\Crusader Kings II).
THEN check your documents and you will notice the game is there
C:\Users\(YOUR USERNAME FOR YOUR PC)\Documents\Paradox Interactive\Crusader Kings II with these files inside ( gfx,logs,mod,dlc signature ,pdx login).
Launch the game and you will see the launcher appearing at least it did for me...
if it will work for you ....then drink a beer on my name
I hope i helped you .
