[CLOSED] I have an issue with my xbox, maybe someone could help ?

So my xbox decided to stop playing my games...The error code 0x80831002 With a message that says (translated from French) :

Code:

[b]A problem regarding your games occured.[/b]To play, you must delete and synchronize them again. To do so, go to parameters > system > storage, then select Erase the downloaded local games. They will be synchronized from the Xbox Live next time you
will play the game. (0x80831002)

Even after doing what is said, it doesn't seems to work. The console restarts (which is supposed to happen) but when I launch the game back, the same message happens.

I've reset my xbox entirely, and it didn't fixed the issue with AC Odyssey. So I uninstalled it, and installed Forza 7 instead, but the same message appears.

I've also tried doing a full power cycle, but no luck there.

One thing that is relevant to note is that upon launching Forza 7, the initial loading screens are very laggy and long, and then this message pops up...However, the game still loads in the background, and at some point, the game even starts and gets to the
game's menu where the soundtrack is playing, everything is moving correctly (in Forza 7 you see your character moving around by his car's side, and despite the message blocking the view, I could see my character's shadow moving on the ground of the garage)
as if the game was running perfectly fine. However, I don't have any option to just close the message and play. It always results in the game closing.

Should I try to install another (small) game on the xbox to see if it keeps doing this ?

NB : I do not own a single disk copy for xbox one. I only have digital copies. I can't afford to buy all my games again on disk copies.
