If you find that the game’s resolution is weird, looks zoomed in, or if the UI is too big and you can’t access the options or play, you should be able to reset the game to its default setting values by deleting a file called "kplayerprefs.yaml" in the OxygenNotIncluded folder found in the documents folder on your computer.
To do this, go into your documents folder at C:\Users\{Your Windows User account}\Documents\Klei\OxygenNotIncluded\ and delete the "kplayerprefs.yaml" file.
From there, launch the game once more and you will find that the resolution and UI scale have been reset to their default settings.
