Have you played other Ren'Py games (many other visual novels)? I wonder if this is isolated to just Cosy Cafe, or Ren'Py in general. Checking my log file from a normal start, I see the same line about "Display Info: None", so that might not be the actual error.
However, on searching "renpy white screen crash" I found a renpy issue thread #6558 on github that mentioned this issue with NVidia xx60/xx70 cards running driver 576.xx or later. The NVidia tech mentioned that downgrading to 572.xx seemed to fix it, but personally that sounds more like a bandaid than a real fix. I didn't see a resolution for it in the thread. You mentioned being on a laptop, and it looks like you already tried to set Windows DPI/scaling to 100%. Did you try holding shift while opening the game to change renderers? Otherwise, I'm not really sure how to help.
