This might be an issue with the WebView (the display tech we're using for the menu), it should display a message to download the appropriate component to display the menu if you don't have this installed already on your PC, but we'll check that again and see to include a proper fix in our next update 🙏
We just deployed a new version which aims to auto-download the appropriate version, or ask you permission to do so if needed. It can cause issues if the Windows you're using has been modified or is a LTSC version, but this update should help anyway.
You can download it right now from the game page, tell me if it helped solve your issue. 😄
