Module crashes Foundry when importing certain stat block

[GafferSwanthold]

I'm trying to import the Tooth Fairy (https://www.d20pfsrd.com/bestiary/monster-listings/fey/tooth-fairy/) stat block, but (although I've tried multiple versions), the module seems to crash Foundry before it even finishes processing. I finally started going line-by-line, but even then it froze within the first dozen lines.
Unfortunately, I'm not getting any errors to correct, because the page freezes before I can troubleshoot.
