Unable to Complete my Device and Service Repair order (Xbox Series X Issues of turning of...

Hello,

I was able to buy and play my Series X only 4 days after the launch and was pretty excited but have ran into certain issues myself that have led me to wanting to order a service and repair.

Firstly the Issue with the Xbox Series X:

Luckily I've only encountered one issue with my console but unfortunately it a big one. My series x seems to turn itself off when playing certain games such as NBA 2K21: Next Generation. So far it has only happened twice whilst playing other games such as
COD: Black Ops Cold war whilst on 2k it literally crashes my system every 30 minutes or so and i've lost time of how many times now. Btw my record on Park is 167 W and only 42 L and 38 of those Ls are from my system turning off (and was winning ffs) and it
has made playing 2k unenjoyable. Now obviously this sound like a game issues right ? well it's been over a month and a half since the game has been out and it has went through it share of issues... but the crashing does not stop and it's not a game crash or
getting kicked from the servers it is my whole console crashing.

Tried Counter measures:

-Hard Rest

-Console Reset (having to re-add my account and etc.)

-Uninstall the game and re-install

-Place the console with plenty of air flow and and additional fan blowing on it to keep it cool

-Part of the Xbox game Preview Program (beta) in which I get software updates months in advance of the public and seen no improvements

-Lowered my resolution from 4k to 1080p

-Cleared all local 360/game unused data

None have worked.

After all that i've then started to look for what others had issues wise and specifically with Nba 2k21 Next Gen and from certain individuals i was told that 2k support has stated that this is an issues of MS (Microsoft) hardware and not the games. Which
I don't know if it is valid however the only options I now have is for my console to be inspected to see if there's any hardware faults.

Issue with the Device and Service Repair order is the final issue I currently have. I am able to go on the Microsoft page with service repair, logged in and my Series X is registered under my account and am able to select it to start the order. Once I get
past the delivery section and get to payment & review a deadline happens. The page redirects itself back to me having to re-login and places me back all the way from the start (issues type) and never able to complete my order.

I have tried to use one of the contact support consisting of chatting with a fellow gamer in which the support was appreciate in which all those countermeasures from above were tried because of that support but at the end didn't help and never was given
the help on completing my order. I have then tried to go through the system on different internet browsers, from pc to phone to xbox to laptop, all had the same result.

In short if anyone has been having the same issue would be interesting to know if any certain correlations are occurring here, or any advice on whether this isn't a hardware issue and any other possible ways of fixing the issue or finally if it is a hardware
any help/advice why I can complete the order.

Thank you and any advice or help would be grateful.

:)
