Hi,
Before commenting suggesting to use AnyRes, use command line arguments, or to set the settings.cfg to read-only, I've tried it all and it does not work.
I've run into a problem. My installation of Kerbal Space Program keeps resetting itself to 720p windowed. Whenever i try to set the resolution in the in-game settings menu, it works and even scales the ui correctly. However, whenever I click accept or cancel to go back to the main menu (and re-enable 3d rendering) it resets itself to 720p windowed. No matter what I try, no matter how many forum threads I search for, no one else has had this problem. Any and all help is gratefully appreciated.
Additional context: settings.cfg shows the resolution as 1920x1080 fullscreen, but no matter what the game always launches as 1280x720 windowed.

Full modlist can be found within the log file. I have also since deleted the outdated version of ModuleManager, to no effect.
RESOLVED:
I hard restarted my pc after removing the outdated ModuleManager, changed the resolution in the main menu settings (to no immediate effect), then loaded into a save and entered the VAB. Once in the VAB, I used the AnyRes Menu to select the correct resolution, which finally worked.
