I just had this crash on my server as well, the stack trace matches exactly. One of the players that was online right before the crash claims they died and then the server crashed; the other player was doing inventory management with a chest. I've attached a log for this report. Server is on 1.18-pre7.

The issue definitely seems to stem from worldgen trying to generate a village. I was trying to fill out a map and when I got close to a certain chunk, my server crashed and presented similar logs as the ones attached, referencing the minecraft:village structure. I restarted the server, connected to it, and after several seconds (while it loaded the chunks around me) it crashed again. I restarted the server once more, and this time ran in the opposite direction I had previously been traveling. This time the server stayed on without crashing, presumably because the chunk with the village was far enough away that it wasn't being loaded.
