Forza Horizon 4 crashing after achieving autumn season.

Do you have your Microsoft account connected and the game have permission to access it?

Hi Martin, my name is Rodrigo. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I am sorry to hear that.

Please, uninstall the current Graphic Card drivers.

Open the Device Manager window by pressing the Windows Key + X and Select "Device Manager".

Select Display Adapter > Right-click the device, and click Uninstall Device > OK

Then, restart your PC.

Then enter your graphics card manufacturer page and download and install the latest drivers.

Let me know if it works!

Hi Joakim,

Sorry to hear Forza Horizon keeps crashing right after the picture.
If Forza Horizon 4 is disabled from being a background app it may crash or hang when suspending and resuming. check whether the setting is set to Off: Privacy > Background apps > Forza Horizon 4 > Off. Please keep this setting On.

I hope this helps ^‿^

Also you can try to contact support on forza forums.

Hope they will help you around there. Sometimes achievements just show up after a while. If not, try support.

Forza 4 has seasons Summer, Autumn, Winter and Spring it changes each week on a Thursday I think. I'm not sure you'd have to wait though, during your first few goes of the game you'll get to try a race in each season if I recall correctly.
