Have you tried resetting your console? If not to do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.

Hi there,

Since the items have been downloaded have you done a full power cycle of the console?

If you haven't, you can follow the steps
here.

That's one thing that will clear up a number of game launch issues.

I agree this is a profile issue, my Kinect takes ages to recognise me but my family member it does instantly and they never have the splash screen issue and programs i.e. Xbox fitness load so much faster on other peoples profile but on the same Xbox one,
does everyone with this issue have a 360 ? I wonder if there is a profile conflict

had similar problem with wolfenstein except the game just did not start at all. I found it needed another 7gig update which I think was problem. maybe some of the games that act up are actually updating in background.

I'm loosing the will to live, spent £600 when the machine come out, and another £120 in games since and the only game that doesn't crash out after 10-15min of starting it is fifa!! Just bought plants vs zombies and the game is ruined by the machine just
throwing me to the menu screen, I'm sure the major rival console has issues to but buying this console after being a xbox fan for 10 years and not being able to use it for what I bought it for is starting to grate BIG TIME!! I've hunted hi and low for a fix,
I've hard reset, I've uninstalled and re-installed I even downloaded rising dead, did the same, went bought the hard cd version and it does exactly the same!! I've never been so frustrated with xbox in my life, crying shame as it' could really be a great console
had it not been for this consistent problem. Even called xbox and they had no answer to my problem just have me my download purchase money back. This needs fixing or I will seriously consider moving the "the other side" ... Don't know if anyone from Microsoft
actually reads this forum, but I'd love to hear back from you!!!
