Minecraft version 1.16.4 doesn't load my data from version 1.16.3

For some reason, when I launch Minecraft version 1.16.4 it kind of reset the game. All my single-player worlds and multi-player worlds were gone. When I relaunched the game in version 1.16.3 all my worlds were there, but I couldn't play on multiplayer servers or realms. Is there any way I can make it so version 1.16.4 loads all my data from version 1.16.3?
