Having the same issue when I hit new game. How did you uninstall it? Since there's no real installation process. I deleted/redownloaded it but same issue.
Right next to the run button, there's a settings icon. In the settings window, there's a button saying "Administrate". Click that, and there should be a button saying "Uninstall now". Do keep in mind I translated these terms, so it might not be the exact phrasing in English / your language.
