Issue: Game crashes with ClassCastException in CarryOnDataManager.getCarryData when loading a save. The error appears to be related to casting ServerPlayer objects.

Steps to Reproduce:

1. Launch Minecraft with the above mod list.
2. Load the save file.
3. The game crashes with a ClassCastException immediately on load.

Troubleshooting:

• Removed Carry On, and the crash stops, confirming this mod as the cause.
• Tried disabling mods related to entity handling, such as Entity Texture Features, Entity Culling, and NotEnoughAnimations, but the issue persists with Carry On enabled.
  Disabling CoroUtil and Dynamic FPS did not resolve the issue, so these are likely not direct causes.
• Disabled every mod except Carry On, issues still persist
