Failed to Quick Play: Could not find world with the provided identifier

This message means that the game immediately tries to join a specific world via the new quickplay system, but the world cannot be found. This means that the instance of Minecraft you're currently launching is misconfigured. Most likely the name of the world is incorrect.

If you're using a third-party launcher, please contact their developers.

If you're using the official launcher, please provide the name of the world folder you're trying to launch and the version json file for the instance of Minecraft you're trying to launch.
