Game Crahses when I load my redstone creative world

Since the recent update I can no loger work in my redstone creative world. As soon as the world loads and I move the character everything locks up and a few moments later the game crashes back to the dashboard.

I dont know how to export a world from the console so I cant send you a copy of it. But it was originally and xbox one version imported into bedrock 6 or 7 months ago.

I guess you will be forced to close this issue as unrepeatable but please note that this is a serious issue for me I have a tonne off contraptions on there that exist only there. and not being able ot access it is reasonably upsetting.
