Symptoms

I can update the user.reg and userdef.reg in the games pfx directory to UK international settings:

[HKEY_CURRENT_USER\Control Panel\International]
"iCalendarType"="1"
"iCountry"="44"
"iCurrDigits"="2"

[HKEY_CURRENT_USER\Control Panel\International\Geo]

But When I launch the game somewhere between booting and getting to the main menu the user.reg is changed to US:

#time=1d95a4568c951e8

"Nation"="244"

Now any online matches will report I am in the US and any local European players may reject to play me.

I have also tried updating the registery with protontricks but it is always changed back to US when playing the game.

This is not a new issue it has always been like this.

Reproduction

Launch the game and start a Online match and create a session then you will have a red US map with your player stats but for me it should be a blue European map. This map represents your location to other players I believe this will also effect match making with local players in general as it thinks I am in the US.

The report names no source files, tests, or entry points. Start by launching Tekken 7 through Proton Experimental and reproducing the locale change before an online match; done means the configured European locale remains in effect and the game reports the expected region instead of US.
