I began playing this game last year, and I after 1 year to play this game again yesterday. It worked fine.
Today, when I started Prison Architect, there was no text. The only thing I could read was 'Prison Architect', the name of the rooms on the floor in the main menu, and the title of the main menu.
When I start normally in windowed mode (or in safe mode), the text is shown, and when I switch to fullscreen, it continues working. I have to do this everytime I launch the game for it to work.
Here are screenshots of the main menu without the text:
Thank you in advance
