1.19 world crashes in 1.20 when entering previously unloaded chunks

My 1.19 Minecraft world runs fine with the new 1.20 update until I enter an area that had never been loaded before the update.  I basically get within render distance of a cherry blossom and the game locks up and gives me a message that my world is corrupted.

I have a backup saved and can reload it to continue playing, but cannot enter any area that hasn't been loaded before the update or the game will crash.
