One of the players on my server has been experiencing this bug.

Version: 1.20.1 Forge
Modpack: https://legacy.curseforge.com/minecraft/modpacks/the-pioneers

After about 5-10 minutes online, when near a dog, the player in question gets a black screen and has to force the game closed. Player moved the dogs away from them and is no longer crashing.

Also using the Better Dogs x Doggy Talents Next mod, and the dogs were skinned with wither skeleton and akitas

Log: https://gist.github.com/BBoldt/d61d3756eb2e09ecf22f18c6efb0cf72

The log mentions Doggy Talents as the reason for crash.

Hmmm.... it is abit difficult to pinpoint the issues based on the log since there is almost no reference to DTN in both.... It maybe the renderHealthInName bug that caused this but i am not sure, could u try to update to DTN 1.18.8?
