My forza Horizon 5 game doesn't get by the loading screen after hitting continue to go into...

I have updated my post to reflect my hardware, as well as fixed the link.

I have to reset my router since the default password isn't working and I am in NETGEAR's bug where I have not set security questions but it is asking me for them to reset my password. I will have to do that outside of work hours since I am not the only one at the house working.

Part list link appears broken.

Please go into the permissions and make sure it has access to your account

Do you have the Xbox Live ports open on your router?

Problem is back. It either is the new preview update from this morning. Cause its messing my Forza 5 game up. Seems like some of the race tracks on Forza 5 are loading way to long to the point it doesn't load and just continues to play the music. Then
forced to dashboard the game. Then the problem starts where it doesn't want to play any games. Then I have to go back to unplugging everything and plug it all back in. Never had any problems with Forza 5 till today after the new preview update.

Go to Home Screen.

Click on My games and Apps

Select Forza and Hit Menu

Select "Show all Addons"

You should see your cars in here.

Install them

Load Forza 5

buy your new cars.

I have run up to 4 games without problems, Halo Reach is one of them, the Forza Horizon 4 game attempt to load with a little screen but the Windows closes after 1 microsecond and does not continue loading. I doubt If the gaming does not support ddr3 memory
or something, but it's a memory standard and I dont understand witch reason is causing the error.
