Consistent crash after approximately one minute on XBOX One

On the XBOX One platform, I have a saved world that is approximately 1.5 years old.

With the most recent updates (the one just before 1.17.34), I experience a consistent, total silent crash after starting the game and waiting for one minute.

Ordinarily I wouldn't care but I've invested a lot in this world.

Also, I am a former software test manager who worked at Microsoft. So if there's anything special or more technical you'd like me to do to help you track down this issue, I may be of assistance. Feel free to reach out to me directly. I'm in the Redmond area just north of the Main Campus.

Thank you very much.
