Hi Casper, I'll try to help you. The game crash immediately after selecting a character or does it take a while?
Do you see the loading?
I think the problem comes from the RAM, because it needs a lot for the initialisation.
I'll create a savefile for you to see if it crashes only during the creation, drop it in:
C:\Users\YourName\AppData\LocalLow\Le triangle à l'harmonica\Quartier-Maître
WeTransfer link for the file: https://we.tl/t-aEX41McvhH
Your screenshot show me the folder of the game, but you have to go to the folder of the saves on your PC. You have to go on your hard drive, follow this path:
C:\Users\"YourName"\AppData\LocalLow\Le triangle à l'harmonica\Quartier-Maître
Replace "YourName" by your specific name folder (it's the red square on the screenshot), and then add the file I send you, or replace the one you have in this folder.
Normally the folder "AppData" is hidden, you have to type it manually in the path bar.
Then you'll a game already created on the titlescreen of the game. So we can see if your problem is only during the creation of a game.
Oh also sorry for borthering you sir for asking too much,i'm very thankfull you are trying to help,but i literally cant understand since i checked the files inside the game and i cant find what you are saying,if you could do a video if its asking too much on what to do,i dont know if i extract the file to local low or what since i cant find the french text (i think only the demo has the text in french)
