Whenever I try to run TH10, it just displays as a black box in the top left corner of my screen, and no audio plays. Any suggestions for how to fix?

few question for you getnts, is this a good place to start the touhou series? is the menu in english? do the touhou serires go on sale often?

just bought this game and when I play the dialogues don't show up and it's just a blank text box (i just have the vanilla game, no thcrap or anything)

On steam deck I can only get two buttons to work. Escape bounded to B and Enter to A work , but nothing else. Any ideas?

Everytime I boot up the game in fullscreen, it just turns into a black box on the top right side of my screen. If I choose to not play it in fullscreen, the screen is then really tiny. Touhou 10 is one of my favorite touhou games, so I would really appreciate if anyone could help me out. ...
