March 27, 2024: The game code has been changed with a recent update. Although it's possible to rework the solution to restore its functionality, it seems unwarranted while Lyall's fix still works and seemingly achieves the same goals. Let me know if it ever stops working and I will have another look.
The solution removes the black bars from the game at 21:9 and wider resolutions.
- Download the archive at the bottom and unpack it.
- Launch the game, followed by the tool.
- Press the key as instructed to toggle the fix on or off.
- Select and apply any in-game resolution or press Alt+Enter in the game twice to fully apply or undo the fix.

Tested on the latest Game Pass version at 2560x1080, 3440x1440 and 3840x1080. Tested on the Steam version externally at 32:9.

Credits to @Lyall for testing the solution and for the idea that led me to correcting the pointer constraint to 16:9, making the menu navigation experience much smoother, especially at 32:9. You can buy Lyall a coffee as well.
