my girlfriend recently updated from 1.17.0.34 to 1.18.0.21, and the usual, the worlds disappeared, so i helped her retrieve them. However, it did not work, the worlds did not show, even if the methods to retrieved them were done properly. she then decided to leave the beta program and downloaded the public version, and to our surprise, the beta worlds were displayed
