How do i set my settings back to borderless windowed??

Foxphor

I pressed F11 in-game and it switched to fullscreen.

I have to aim away from the buttons to click them now!

I tried to:

• change the resolution in game data
• reinstall the game
• Change the settings in game
• change even more settings in game data
• verify the files

I don't know what to do at this point. Somebody here knows how to fix this???
