[Bug]: A crash from Easy Anvils and Inventory Tabs in a lage modpack.

[ghost]

Minecraft Version: 1.21
Mod Loader: Fabric 0.16
Mod versions: Easy Anvils (21.0.2), Inventory Tabs (1.3.3)

When trying to load a world with both mods installed in a large modpack I'm playing, it prevents the player from entering said world due to "corrupt data". The player also is unable to create a new world as it just crashes the game.

After some investigation, it turns out, it is seemingly due to inventory tabs:

After removing either Easy Anvils or Inventory Tabs from the modpack, the player is able to load any existing worlds or create new worlds. Judging from my investigation, it seems that Inventory Tabs is the main cause of the problem, but I could be wrong, given that it is in a large modpack.

I've submitted this crash to Fuzs, the mod author of Easy Anvils, as well. I am submitting it to here as well, in hopes of solving this issue more quickly.

That's a CME on a non-concurrent hash map apparently on this line? https://github.com/sisby-folk/inventory-tabs/blob/1.20/src/main/java/folk/sisby/inventory_tabs/TabProviders.java#L175

does this still happen if you turn configlogging off in the config?

To my surprise, it doesn't crash once configlogging is off. I'm able to create new worlds and load them just fine.
