Oh no :( Since you use 1920x1080 I'm guessing it has to do with a scale setting in Windows while the game starts with a large window size. Here I see the game opens with the top part outside your display (this is likely the issue if you have a >100% scale setting under Windows System > Display for 1920x1080) so that the settings menu is not visible. In this case, if you want to keep your scale setting >100%, one option could be to go to the game installation folder, then the Saves folder below it, and open the file settings.txt in e.g. Notepad. In this file, change the number after xtiles: to 8: and ytiles: to 4:, save the file and then open the game. This will change the window size to 1024x512 so that the window should be small enough to fit in your display, and then you could change it in the settings menu afterwards.
Once the full window is visible, the window size can be changed in the settings menu, which is accessed from the gear icon in the top left - the yellow arrow below:
In this settings menu, here is a window size option:
Let me know if this didn't solve your problem or I misunderstood something.
