Minecraft crashes while loading certain chunks

When randomly exploring biomes in my 1.19.1 world I have found out that when loading some structures (for example Ocean monuments and other structures that I had no time to identify) the game crashes with an exit code of -1 with no specific reasoning in the crash report, this also has completely deleted an horse and a donkey that I had previously tamed, with them not being able to be found by a tp command even if I used the specific name of the mob assigned via nametag.

As mentioned in the title the world is loaded with a few datapacks that belong to older versions of the game but were completely usable during my playtime with the structures generated behaving as intended and spawning without causing issues.

I should also mention that after creating a few creative worlds and locating ocean monuments the crashes did not reappear, I also tried to verify if the issue lied with the elder guardian's "jumpscare animation" but the two things do not seem to be correlated.

Now for the list of the datapacks involved:

  • A series of packs by Miles Playz:

These are all packs used.

The world is not modded otherwise.

This issue has already been discussed on the MChelp subreddit (https://www.reddit.com/r/MinecraftHelp/comments/wc64ig/minecraft_1191_world_with_older_datapacks_keeps/).

A similiar issue can be found here (https://bugs.mojang.com/browse/MC-252680).

I'll try to respond as fast as possible if needed.

Can you reproduce the crash with only "New Shipwrecks", on the same seed? It seems like the shipwreck is several chunks long, causing the heightmap lookup in ShipwreckGenerator$Piece#generate (yarn 1.19.1) to get chunk outside one managed by the generated chunk region, therefore crashing.
