I can confirm this. It seems to be a random crash.
crash-2024-10-21_16.41.05-client.txt

And I found crash reports with the exact same stack on both Minecraft Forums and Reddit:

So we've got 4 separate reports, which is enough to prove that this is not an isolated case, but a common one.

Considering it's a ConcurrentHashMap and the crash is random, could this be a problem related to multithreading?

Seems to have something to do with the addItemModel function, hope it gets fixed soon .
