I just experienced this crash while playing through the Campaign mode. As other people have already stated, I was seeing intermittent lag during previous levels but nothing too bad. Was able to play through all the levels until I get to the Lando Mission 'Cache Grab' on Sullust. The game freezes and if you hit the Home button the Xbox goes back to the dashboard briefly then reboots itself. It restarts itself automatically.
What type of Xbox One do I have?
The initial launch 500GB plain Xbox One.
What mission is it crashing in? What are you exactly doing before it crashes?
The Lando mission on Sullust. Right at the very beginning level as Lando and Shriv are moving down the path to the installation, if I crouch and try to sneak up on the stormtroopers eventually the game freezes as the stormtrooper dialog begins, the sound goes haywire and begins rotating around each channel on my 5.1. home theater system. Occasionally bits of dialog will play but the game remains frozen. If I then hit the Home button to go back to the dashboard, the screen goes dark for several seconds, the dashboard appears for a few very brief seconds then the Xbox reboots completely.
Have you tried playing the campaign mission from the start? Does it still crash?
Yes. I just reinstalled and started playing the Campaign from the beginning. The other levels played normally with no major issues. Some lag spikes but they were brief and the system recovered. Every time I try to start the Lando mission on Sullust the game eventually freezes and I get the Xbox reboot.
Is the game installed on the internal hard drive?
Yes, it is.
Do you have any USB devices plugged into the Xbox?
Not at the moment, no.
Have you tried a fresh reinstall?
Recently, yes.
