can you help me with this problem.. i cannot lunching stronghold crusader 2 in steam

After loading the game I get the error "failed to initialize engine". I read on the forums that deleting the file in my documents folder would fix it and it worked. But I have to do the same thing every time I enter a game. Moreover, I can't play full screen. I would be glad if I get help from someone who has experienced a similar problem and solved it. It negatively affects my enjoyment of the game....

I can't launch the game in full screen. I tried the settings on the game but also the modifications directly on windows but nothing works. I think the window is bugged because it seems to be in a borderless window but without being because I don't have the window options at the top right. Could you help me? Thanks...

l have read some comments which said to change fullscreen from true to false, but nothing is changed

I did everything I could find from verifying files, reinstalling steam, deleting the save folder, reinstalling vcredist and dx, including netframework etc. Nothing seems to work, when I click launch it does nothing and no warning messages at all. But all my other games runs fine except for this one....
