The game kicks me out to home

Try clearing your cache. Unplug the power brick from your Xbox One and hit the power button a few times, this will drain any energy left in the console. Wait for about 30 seconds, plug it back in, wait another 30 seconds or so, turn on your console. I know
it sounds odd but I was having a similar issue with a different game and doing this fixed the problem. Hope that helps

Hi Aldo E, my name is Daniel. I am an independent advisor who is willing to help you.

For me, it is an honor to write to you and try to help you in any way possible, for my part I will do my best to try to solve any questions/problems you are presenting.

I'm sorry to hear that you are having this problem with the game Fortnite, with the intention of helping you after doing some internet searches to gather information about it, I suggest you follow these steps:

The first thing we need to do is a power cycle with the console, it seems to be a fairly basic solution, but in some cases it can work.

1. Turn off the console by pressing the Xbox Button on the front of the console for about 10 seconds, until it turns off completely.
2. Disconnect the power cable from the console. Wait ten seconds.
3. Plug the console power cable back in.
4. Press the Xbox Button on the console to turn it on again.

If these steps don't work, we'll try logging out of your Xbox profile and adding the account again.

1. Press the Xbox button to open the guide.
2. Select Profile & system > Settings > Account > Remove accounts.
3. Select the profile you want to remove, and then select Remove to confirm the operation.

To add again:

1. Press the Xbox button to open the guide.
2. Select Profile & system > Add or change > Add new.
3. Enter the email address of the Microsoft account you want to add and select Sign in.

Note: Make sure you don't select Get a new account unless you want to create a new Microsoft account.

Some times the game kicks me out and takes me back to Xbox Home....

Hi!

What do you mean? Does it bring you back to the xbox dashboard once you run it?

you can try reinstalling the games again, maybe a file got corrupted as you were downloading the game

if GTAV is a physical disc, try to reinstall it again without patching at the same time

Hope this helps!
