Unhandled Scripting Watchdog Exception

My system updated to Minecraft PE 1.19.20 yesterday.  I play for about four hours before getting the error message attached and it kicking back to the load game screen.  It has done this with EVERY world I have, regardless of age or file size.  I cannot open any worlds - I do NOT play on a server but by myself on my iPad.

This ‘feature’ appears to be something in the notes for the 1.19.20 update but I cannot find a way to turn off or change the parameters so that I do not get this message.
