non-existent error codes

when I start some of my games in my xbox one it appears

"Something went wrong, try again" and there is always an error code, but every time I try again the error code changes, and when looking at
Xbox.com/errorhelp the result is that the code does not exist, in
end

I would like to know if there is a way to fix it.

 

Destiny won't download properly.

Every time I try to start up destiny it says that it needs to download an additional 1gb and when I press the finish installing button it just says that something went wrong. I downloaded normally without any issues but this is just preventing me from playing
it.
