Xbox Series X - Black Screen when launching

Hi @RicME85 Can we try the following:

• Quit the game and other running apps from Quick Resume (For Series X|S consoles)
• Remove any connected device, or additional USB's from the console then restart the Xbox and check
• Check for updates 
• Persistent Storage 
• Go to settings > Select Device & Connections > Then Blue-Ray 
• Select Persistent Storage > Clear Persistent Storage 
• Alternate Mac: 
• Go to settings > Select General  > Then Network settings 
• Go to advanced settings > Alternate Mac address > Select clear 
• Select restart 

Unfortunately still the same thing happening.

It's odd, the game is clearly there as I can hear the menu music and if I keep hitting A then it advances to loading into the game, if I move the stick it sounds the character is running around on dirt/gravel but the screen is black, almost like there is no signal being sent to TV it's that dark but bringing up the guide shows there is a signal.

I was having the same problem. Deleting my save (both local and cloud) and clearing reserve space fixed it. Also this time I did not change any settings. 

I deleted all the local files including the reserved space like the poster above you mentioned and still the same result.
