Can't load the page and even if the Google Stadia Shop page loads I can not press the preorder (German: "vorbestellen") button.

Correct URL where you can get to the Stadia Shop after logging into your Google account:
https://stadia.google.com/game/cyberpunk2077
Please describe how to reproduce.
Initial intention: Buy the Cyberpunk 2077 game on Google Stadia
System: Windows 10 Pro 64 Bit German
Location: Germany (the Stadia Shopping page switches to German automatically)
Browser: Google Chrome 64 Bit version 86.0.4240.75 (fresh installation)
Additional information: AdGuard legacy browser assistant is used (what works in all browsers)
How works after use:
@@||stadia.google.com^$stealth
I suppose guilty:
/cookie_consent_
fix:
@@||gstatic.com/brandstudio/kato/cookie_choice_component/cookie_consent_$script,domain=stadia.google.com
Without script I can not see gallery and buy.
Will be nice also test disable stealth mode by rule: https://github.com/AdguardTeam/AdguardFilters/issues/65664#issuecomment-709997893 or in Windows App.
Added an new user rule (see screenshot)
@@||gstatic.com/brandstudio/kato/cookie_choice_component/cookie_consent_$script,domain=stadia.google.com
Cleared the Chrome browser cache by pressing chrome Strg + Shift + Delete (Advanced > All time > select everything)
Repeated my 10 steps process but the page is still black after google login

Disabled the AdGuard Stealth Mode and everything works fine.
I think it is the Geo-blocking of the Stadia Shop.
This not like geo-lock, normal available in Germany.
Disabled the AdGuard Stealth Mode and everything works fine.
So, now active again and test this rule:
@@||stadia.google.com^$stealth
https://kb.adguard.com/en/general/how-to-create-your-own-ad-filters#stealth-modifier
if no broken by disabled WebRTC should help for more people without manually disable Stealth mode in settings.
Enabled Stealth Mode. Cleared the user rules from before. Added the @@||stadia.google.com^$stealth rule. Cleared Browser. Repeated the test process.
_Conclusion: It works, if the Stealth Mode for the Stadia site is disabled._
By the way if stealth mode is enabled the 2FA Google Login (the confirmation that pops up on your smartphone) does not work and I have to use SMS verification.

Google 2FA Login seems to work if you disable the "Hide your Referrer from third-parties" setting in the Stealth Mode settings.
But this does NOT fix the black page and initial problem after the login from the Stadia shop, so I still have to disable Stealth Mode for stadia.google.com (with the user rule).

So this need wait for idea by @AdamWr / @Alex-302 / @BlazDT if possible made.
The "safest" thing to do would be to stop using stealth mode if you often you play on the stadia.
Final note: I Reset setting to defaults in AdGuard and then enabled Stealth Mode and repeated the test process and everything seems to work.
I still don't know what (custom) option in the Stealth Mode setting was causing the problem, but this seems to be a problem created by enabling too many options in the Stealth Mode tab.
I still recommend analysing whether it is right to block "cookies" file anyway, so that I do not see the gallery and the purchase option does not work.

First, I hope I understand you correctly... 馃
I don't have any problems anymore after I reseted the AdGuard setting and used the default Stealth Mode options.
I also tried the "cookie rule" posted in the mentioned comment, but it seems it did not change anything and I can see the Stadia gallery and even just purchased a game without any problem.
See my comment:

Note:
I use the "AdGuard Annoyance filter" that blocks cookie notices and use default Chrome setting with default cookie setting and third-party cookies are allowed, perhaps that is another reason some people have problems with Stadia.

Hi. Probably by custom referrer or custom IP(when you enter your own value to the text fields). Please reopen if an issue will be reproduced again.
