Do you use the iGPU or the dGPU on your computer?
Did you enabled the "DirectPlay"? This is located on Control Panel > Program and Features > Windows Features > Legacy Components > Direct Play
Now, let's check about your resolution
2560x1440 is a 16:9 Resolution, so you should go to edit some files in game
In game data of Freelancer DISCOVERY inside "Interface" there is a file called "HudShift.ini"
[HUDShift]
Horizontal = 0.17
These should be your datas: ; 16:9 (1280x720, 1440x810, 1600x900, 1920x1080, 2560x1440).
[;HUDShift]
Horizontal = 0.17
If not change it, after it, probably you could need the d3d9 file or something like that that could help with it ...
As far i am able to detect, try checking your log file in Documents > MyGames > Discovery Freelancer > DSAce.log ... try check if there is a hidden message ....
Ah! Remember the game should not go beyond the 144-155 FPS or game will and probably crash while pull a cheat message cause of it ...
But as i cannot know your hardware i can't explain you better, if you brief me with it, i could try to locate a better answer and maybe help to find a solution to the issue you are showing to us .... because "Game terminates" could mean a simply driver failure to a whole game or computer failure ...

As a workaround in the launcher (cause you need launch the game from launcher) try enable the Desktop Resolution, if that don't work, move the slider and put a resolution like 1920x1080 for example, to see if Windowed Mode of the game keeps crashing so we can look further into the issue and reduce culpability and find a solution faster
P.D: Don't put a Title in Mayus, cause in Internet "It's like you're screaming" and we don't wanna scream right? we should be polite to get a polite answer.
