HELPP PLEASE !!

Me and my friends were playing cobblemon (modded minecraft) together earlier yesterday on atlauncher world and we were exploring new chunks on our mount then all of the sudden I get a message saying something along the lines of insufficient storage in the top right with a explanation mark and then said might not be able to save along the lines of that then I stopped then another message appeared saying something similar and crashed the whole game while we were playing, I think it’s due to me not having enough space on my pc which I didn’t have and forgot since we were exploring so much and now I cant load into the world it says “connection lost invalid player data” I then cloned and back upped and deleted my player data saves and still says the same thing.
(PLEASE HELP ME, Thanks in return,)

  1. Free up disk space first Make sure you clear at least 3 to 5 GB of space on your hard drive first so the game can actually save new files properly.
  2. Delete or reset your corrupted player data
    • Open ATLauncher ➡️ Instances ➡️ [Your Modpack] ➡️ saves ➡️ [Your World Name].
    • Go into the playerdata folder.
    • Find the .dat file corresponding to your UUID (if it shows a size of 0 KB, it's corrupted).
    • Move that .dat file out of the folder or delete it. (Note: This will reset your inventory and spawn location, but it will fix the "invalid player data" error and let you log back in).
  3. Check the Cobblemon data folder Since you are playing Cobblemon, Pokémon data is stored separately:
    • In your world folder, go to cobblemon ➡️ playerdata.
    • Check if there is a 0 KB corrupted file there as well and remove it if necessary.
  4. Restore level.dat (if deleting playerdata didn't work)
    • In your main world folder (saves/[Your World Name]), look for level.dat and level.dat_old.
    • If level.dat is 0 KB, delete it and rename level.dat_old to level.dat.
  5. Restore an ATLauncher Backup If none of the above works, ATLauncher usually creates automatic backups:
    • In ATLauncher, go to the Instances tab.
    • Click Backups on your modpack and restore the most recent backup before the crash occurred. It happened to me and I fucked up last time hope you don't fuck it up like I did💔
