I got a reply for support and they suggested the following…
Hello,
We’re looking into this issue for you and we have some troubleshooting and questions.
Does this crash occur every time in the same way?
Would it be possible to provide a video of the crash in action so we can have more details about where and what you are doing in game before the crash.
Please follow all the steps in this guide before continuing, to ensure that you have tried all of our troubleshooting steps prior My Game is Not Launching or is Crashing on PC
Check 3rd party programs
Please note that there are several program conflicts and issues with 3rd party applications we're currently investigating that can affect performance, general game stability, and being able to launch Forza. This includes any 3rd party programs, overlays or monitoring tools running in sync with the game. If you are using any non-Microsoft programs that are running in the background like overlays or input monitoring we recommend disabling or uninstalling them to see if that resolves your issue. Please note that even if you are not using these tools for Forza they can still run in the background and affect game performance that may cause conflicts or crashes
Update Direct X
Please also attempt to update your Direct X version using Microsoft's web installer at the following link.
