Issue Description
When the Texture Quality is set to Full Res, whether the game applies either Full or Half Res on game startup seems random. Whenever I open Settings the selected option says Full Res, however the majority of the time that the game is launched it is actually in Half Res. This incorrect resolution is applied to the entire game (Main Menu, Vehicle Assembly Building, Cockpit and 3rd person vessel views, etc.) The UI scale is also affected. I set it to 80%, but 80% is only applied to the game when the Texture Quality is also correctly applied. The rest of the time it stays at the default 90%. I can only assume this applies to other settings where I haven't been able to notice the difference. I just started playing a month ago and the issue has been present the entire time so I would not notice if, for example, Terrain Shader Quality wasn't working. Occasionally, the game will correctly apply those settings, though if something specific is triggering whether the settings are properly applied I have not figured out what that is.

I have included screenshots of my settings (the game has only applied Half-Res Texture Quality and 90% UI Scale in the screenshots). I could not locate the output_log.txt file. I have attached debug.log from the game's files which seems to reference an error with the Settings.

Reproduction (Since this issue was when I downloaded the game I'm not certain how to trigger it initially)
1. Launch game
2. Ensure Texture Quality under Graphics is set to Full Res and UI Scale under Gameplay is set to 80%
2.1 Change those settings options if necessary, click Apply then Accept.
2.2 Opening and checking Settings when at the KSC or flying a vessel have the same result as opening Settings from the Main Menu.
3. Exit Settings and check to see whether they were properly applied.
3.1 If at the Main Menu the Kerbal's suit and the yellow text (Start Game, Settings, etc.) have worked best when comparing the Texture Quality.
3.2 If a game is already loaded the UI scale is most noticeable.
4. If settings were properly applied, close the game and perform steps 1-3 again.
