To Reproduce
Steps to reproduce the behavior:

1. Use 'mod and... uh?'
2. Click on 'main menu button/ type stop in dedicated server'
3. See error (in logs)

Expected behavior
the mod to not throw errors when leaving to main menu

Versions (please complete the following information):

• Minecraft version: [1.21.1]
• NeoForge version: [21.1.192]
• Mod Version [InventoryFree-1.21.0-3.3.1]

Additional context
it doesnt do anything particularly bad well i mean your not gonna leave your game and then you pc is gonna just fucking be bricked its more like if your using the mod and then your also making a mod pack after about 50+ restarts the game becomes unplayable due to corruption now that might be because other mods are helping this one speed it up but i do know when i removed this mod and continued my modding adventures i never got a corrupted neoforge jar and i was still able to launch the game btw the fix to that was to remove all my mods and configs make a new neoforge jar and then put everything right back where it was so it was a perfect copy EXCEPT the neoforge jar aka it got corrupted also this is what chat gpt had to say

TL;DR: The problem is with the Inventory Free mod during server shutdown, where it's trying to read a config value after the config has already been unloaded, which is not allowed.

Key Error:

Cannot get config value before config is loaded.

The mod is calling .get() on a ModConfigSpec.ConfigValue during the ModConfigEvent.Unloading phase, which it shouldn't do because the config is already being unloaded at that point.

The error is uncaught during shutdown, leading to:

net.neoforged.fml.ModLoadingException: Loading errors encountered:
Inventory-Free (inventory_free) encountered an error while dispatching the ModConfigEvent$Unloading

This is not a crash during gameplay but a crash during mod unloading, likely causing issues on world save or clean shutdown (e.g., stuck threads or potential data corruption).

Inventory-Free is violating NeoForge lifecycle rules. It's reading from its config in an @SubscribeEvent handler for config unloading, which is too late in the lifecycle. Config values become invalid during that phase.

Repeated stuck threads (AWT-EventQueue, pool-13-thread-1, AWT-Shutdown) are likely from a GUI-based tool or logger (maybe AllTheLeaks, InventoryFree, or a config GUI like Cloth Config/ForgeConfigGUI) not shutting down cleanly.

here are the logs in the server BTW this is in the SERVER not the INTERNAL server
