Win10 Bedrock World Crash on startup

I have a World I started in Minecraft Beta in windows 10 that worked up to v1.4.2
The world would crash (and all past saves as well) when I tried to load it in v1.13.1
The world worked when I loaded it a few weeks ago.
The World keeps crashing with v1.14.1 after the update.
It is a 147.1MB Creative world.
