I would recommend you go into the game folder and delete the options.json file inside the config folder. This will reset all the game options. Then relaunch the game, go into Settings/Options/Graphics, scroll down to ‘Fullscreen’ and set that to ‘Windowed Borderless’. While on that same screen set the Terminal Width and Terminal height to the correct values for your monitor resolution (240 and 66 for 1080p for example).
I believe this will fix the issues.
