bookdatastored crashes when closing simulator

M1 MacBook Pro Big Sur 11.3.1
Xcode 12.4
Developing for WatchOS

I'm getting repeated crash reports in the console from bookdatastored. It seems to occur each time I quit out of the Simulator in Xcode, I don't notice any stability issues with my system or with the simulator or Xcode when this crashes. I'm just getting persistent crash reports from it.

Does anybody have any ideas of the cause of this and how to resolve?
Reinstalled Xcode, and started a fresh project.
