Forza 7 won't start after Fall Creators update FIXED

Yesterday I updated my PC to latest version of Windows 10 and now Forza 7 will no longer start. It gets as far as the initial splash screen then closes after a second or two. No other software seems to be affected

Any hints or tips?

FIXED

I went onto the store and reinstalled the Forza Hub and game now starts fine … watch this space if this changes.
