Thanks for reporting. There really isn't any hint in the log why this would have happened.
It's also a bit odd this has just been happening now, as the version of the mod you are using is older than two years. 😅
Can you describe what you were doing in the anvil screen that caused the crash? And in general what sort of items you had on your player etc. Ideally with screenshots.

The crash occurs once every few hours (6-12) of play; it is a medium-sized server (10-15 people playing at peak times). I haven't noticed that any of my actions cause it. I'll try to get some additional information from the players, but I have a feeling it will be difficult.

It's definitely happening when someone is using the anvil menu, that is clear from the log. The question just is what exactly they are doing haha
I've seen issues that are similar, which are usually caused by some modded items constantly updating their NBT data during some verification, which leads to the container menu trying to process those changes over and over again leading to this infinite loop. It's likely something similar.
