Try these ideas.
Idea 1:
1:
Open a "File Explorer" window and go here:
%LOCALAPPDATA%\Insomnia_v2\Saved\Config\WindowsNoEditor\
Create backups of all of those files by copying and pasting them somewhere else.
2.
After you create the backups, delete all of the files in the original folder and start the game. That should cause the game to reset its settings to the default ones.
If that didn't work, try this:
Idea 2:
1:
You said you finished the game once with a different computer. On that computer, open this location:
%LOCALAPPDATA%\Insomnia_v2\Saved\Config\WindowsNoEditor\
2.
Copy and paste those files to the same location on the laptop that's causing the game to not work.
3.
Open "GameUserSettings.ini" in a text program, like Notepad, and you will notice these lines:
ResolutionSizeX=1280
ResolutionSizeY=720
LastUserConfirmedResolutionSizeX=1280
LastUserConfirmedResolutionSizeY=720
LastUserConfirmedDesiredScreenWidth=1280
LastUserConfirmedDesiredScreenHeight=720
4.
Those lines will match the resolution of the screen of the computer you used to finish the game. Change the values of those lines to match the resolution of your laptop.
5.
Start the game.
If that didn't work, try this idea:
Idea 3 (this should force the game to be in "Windowed" mode as a test, and you could change it to "Fullscreen" later, in the game's settings menu):
1.
In "GameUserSettings.ini", change these lines to a resolution that's LOWER than the resolution of your laptop's screen, so the Windowed mode could fit. So, if your laptop's resolution is 1920 x 1080, change the lines like this:
ResolutionSizeX=1280
ResolutionSizeY=720
LastUserConfirmedResolutionSizeX=1280
LastUserConfirmedResolutionSizeY=720
LastUserConfirmedDesiredScreenWidth=1280
LastUserConfirmedDesiredScreenHeight=720
2.
Directly under those lines, add these lines:
FullscreenMode=2
LastConfirmedFullscreenMode=2
PreferredFullscreenMode=0
3.
Start the game.
Did one of my ideas work?
