Hello everyone, in order to make the game run more smoothly, I switched the game framework from Nw.js to Webview2 in the latest version. But this also caused some players to be unable to save the game.
Generally speaking, this is because the version of Webview2 in the system is too low, causing the game to be unable to recognize your Steam game folder. You can solve the problem by downloading and updating Webview2 on the Microsoft official website.
