This is probably gonna sound very stupid, but how do you get out of the settings screen? On pc.
Can you show me the error message? Also, are you on PC or Mac? In any case, please try out the Web-Browser version of the game instead, it should work flawless: https://tyrving.itch.io/after-years-web-browser-version?secret=2xVhaOotNJrmXN445... (I highly recommend running the game in Chrome or Firefox - the former should work the best in terms of the overall performance.)
