So, I don't think it's a region related issue and I think I might've fixed it (waiting for the launcher to download stuff and all). I just went to the C:\Program Files\WindowsApps\Mutable\100B7A24.oxyna_184.108.40.206_x64__wyfsmff9ynw7j and changed the whole WindowsApps permissions to my local user so it has full control. After that I've set all the executable files in the \100B7A24.oxyna_220.127.116.11_x64__wyfsmff9ynw7j folder to run as administrator and game started updating. I'll wait for it to finish downloading and I'll report soon.
I did the same thing, as well i'm waiting to the game to download again, let's hope that works
