Jurassic World - crashes on start

My child has a Kindle Fire HD 8 (12th Generation), running Fire OS 8.3.1.4. It has Minecraft version 1.19.71. I have no idea what's up with the Bedrock / Java realms platform. It's a Kindle, trying to pay single player. 

I purchased the Jurassic World template, it shows as version 1.0.1.7 in the Create New World menu. 

 

Whenever he or I creates a work and it loads, it crashes after a few seconds.
