Every time I try to enter an old single-player world or create a new one it keeps saying, "Connection Lost Invalid Player Data" I've tried everything I could think of to fix it, including restarting Minecraft, logging out and logging back into Minecraft, and uninstalling the launcher and re-downloading it. The only way I can enter a world is by deleting the mod. It's weird since every version of the mod except the 1.19 version works fine.

Please append the latest.log
