What game version? I haven't had this on the latest for MCv1.18

Same problem. Here is the log - latest.log

I cannot seem to reproduce this at all. Please be sure your running the latest version of the mod, as the dragon_breeds registry was implemented fairly recently.

is there any fix for this yet

It was an incompatibility problem with some mod. I already deleted it many months ago and now I can't remember which mod caused it.

This seems to be a rather rare issue with a particular incompatible mod. I wish I could name which one it is, but no one has seemed to figure it out. Closing this.
