Game streaming - game capture not working, window capture works

[Mundi]

HI, I am pretty new here, so I apologize first if I am writing in the wrong section!

I need help.
I want to stream game or something else with obs. If i try to stream screen or any window no problem, but when i want to stream a videogame i have several problems.

If i try to stream starfield from xbox app and:

- use game capture mode, no video is acquired (audio is). I haven't find a single solution to let the video work
- use window capture work perfectly video and audio, but the video has the "yellow square" that tilt me. I have no option to remove it


Is there a solution to:
- use game capture with games
- alternativly, if is not possible to use game capture with games (?), is there a solution to remove the "yellow squared border" while gaming? i know that is a window security feature, but i want to decide where and when use it

I am up to send any screen to better understand the situation

I attached 2 screen of game caputre and window capture

My configuration is below:

Not a laptop

rtx 4070ti
13600kf
32gb ram ddr5

P.S. i am Italian so something can be in italian in screens

Spoiler: images

Found a solution! Was rivatuner that, for some reason, blocked that. Just enable the Stealth Mode su On and will fix it
