there is a problem with your saved games/startup error

my xbox one x causing problems and i iought it less than a year and a half ago.
the broblems started around a half a year ago.
when trying to install a game it says "installation failed", sometimes it finishes the installation but it's very rare though.
sometimes the console just kinda "crashes", the screen is going blank gray and the console doesn't respond. when turning off the xbox or trying to restart it, it will cause startup errors, most common E105, which wont go away without reseting the console
to it's factory defaults, and even after this it will just show another error, E 102 which i have to get rid of by either reseting it to factory defaults via usb or updating it offline.
another issue that i'm having is that the games won't save capaign saves, and every time i try playing any campaign of any game, after dying/restarting the game, it will say "there is a problem with your saved games..." which somtimes also appears when
playing online games without any save file, normally to fix this i'll have to clear local saved games, but this solution brings me again to the same place where i get a blank grey screen and no response from the console, and after restarting i have to go through
the startup errors again.
basically the console is bricked from my point of view cause i really cant do almost anything with it.
im using wired network connection and i've tried basically every single solution i coul'd find on the internet but it seems like all the time im doing the same thing and getting no results.

seems like there is a problem with the internal hard drive from what i saw on the forum, but it also seems like it may occur even after changing it to an one.

i'd really appreciate any help or ideas of what may be the problem and how to fix it. thanks.
