Xbox one - Blank screen while starting forza motorsport 5, after studios title appear

Hey DaringMansha!

I am sorry to hear about the blank screen issues. Just to make sure that we have not missed any troubleshooting steps I would like to recommend a few steps if you have not tried them already.

Give the following steps a shot:

• Press and hold the power button on your console for 10 seconds.
• Once your console is powered off, unplug the power cord.
• Leave the console unplugged for 5 minutes and plug in your console.
• Power on your console.
• Test your Network connections to verify that there are no connection issues.
  

Please keep us updated and we will be standing by to help get this sorted out.

Forza Horizon 4 does not support 2 players on one console at the same time, the Forza Motorsport games for Xbox One however do (that is Forza Motorsport 5, 6, and 7)

The terms you want to be looking for are couch co-op, local co-op, split screen, and some more, if you are ever unsure, feel free to make a post asking

some games that offer 2 players at the same time on the Xbox One, are the Forza Motorsport titles listed above, Halo: The Master Chief Collection, Halo: Reach (which is backwards compatible), all the Lego Video games, Minecraft.

For Forza Motorsport 5, Turn 10 Studios will once again be bringing an awesome cadence of add-on cars. Each month, we’ll be bringing you a new car pack, featuring ten cars to collect, drive, and customize in Forza Motorsport 5. In addition, just like each
car that comes on disc in Forza 5, every add-on car will feature a full Forzavista experience. Walk around the car, check out the interior, start up and rev the engine, learn about the car’s history and performance statistics; you can even add a new livery
design, change the paint color, or tune your car all from the same Forzavista view. Every car has a story to tell in Forza Motorsport 5 and the story will continue to unfold even months after the November 22 launch.
