I’m having an issue where I can’t rejoin my own private worlds in this version. Even if I create a new world and leave shortly after, I’m unable to join it again. The error message “Invalid player data” appears, similar to what happens when getting kicked from a server.
I’ve attached a clip showing me trying to join several of my worlds, creating a new one, leaving it, and then failing to reconnect due to this error.
Steps to Reproduce:
Create a new private world.
Enter the world and play briefly.
Leave the world to the main menu.
Try to rejoin the same world — the “Invalid player data” error appears.
Expected Result:
I should be able to rejoin my private worlds without errors.
Observed Result:
After leaving any world, trying to join it again results in an “Invalid player data” error, preventing me from entering.
Thank you for your report!
