I'm recording calls in Windows 10pro by Alt+WIN+R and its recording video and audio very...

Yes that is correct. I connected to my Xbox from Win 10 and then started the stream. Then on the laptop I used the keyboard shortcut to start the recording (Win+Alt+R). Let the recording run for 2 minutes and then pressed Win+Alt+R again to stop the recording.
I then get a notification that the recording is complete. I then stop the stream and go to the Game DVR page on the Xbox app to review the recording and found that it is only 40 seconds long. I opened the recording folder in windows explorer and it is still
only 40 seconds long.

There are two commands in Windows G of Xbox, one of them is to record your screen from that moment, ie, record everything that you do after the command, this is the command Windows + Alt + R (record from now) **** in this I put the command Windows + Alt
+ G, to "record this", an activity already done in this command, when I go to see the final video of the recording, it all black, with the mouse.

Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

Nasaruddin, the recording system was developed particularly for gaming, so there may be some conflicts if used in other locations.

What you can test, would be to repair the gamebar, and finally make an inbound version of your windows.

Test all these processes, if you don't get any, skip to the next one.

Method 1: Fix Xbox Game Bar

1. On the desktop, press the Windows + R keys, type regedit and click OK;

2. Inside Regedit go to the path HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\GameDVR

3. Click and leave the GameDVR option selected. On the right side of the screen, select ALL keys, with the exception of the (Default) or (Default) key, right-click and click Delete;

4. Restart your computer and test Xbox Game Bar functionality.

Method 2

1. On the desktop, press the keys Windows + R, type msconfig and click OK;

2. In the System Configuration window click on the Services tab;

3. At the bottom of the screen, check the box Hide all Microsoft services and click on Disable all;

4. Click Apply and OK;

5. Restart the computer and test again

Go to your windows update and click on get updates

After updating

See which version is your windows this way, and tell me

The version consists of 4 digits

And then go to the Microsoft Store, select More > Downloads & updates > Get updates.

Update everything in both places, and let me know if it works

Try these procedures:

How to activate Windows Alt G?
If enabled, you can use the shortcut Win + Alt + G to record clips of the last moments of the game. Although interesting, this function can affect the performance of games. Clips: In this option, the user defines the maximum capture time. How to activate Windows Alt R?
Tip: You can directly start recording by pressing “Win+Alt+R”. 3. If the message “Game resources not available“ is displayed, check the option “Enable game resources for this app to record plays” so that it is possible to record the screen of the program/game in question.

Hope I helped, see you soon!

Hi Geri!
Thanks again for your kind reply, Hope you're having and amazing week!

Sadly, those articles have nothing to do with my problem, in the meantime i managed to get a workaround going.

Tab into the game, Press Win+Alt+R to start a recording, Win+Alt+M to unmute the mic and Win+Alt+R again to stop the recording, the thing is, I have to do that every time another window gets focused, which is kind of annoying.
The other workaround i found is setting the gamebar to record only the game's audio instead of the whole pc's, for some reason this fixes the issue, but isn't ideal as sometimes i want to clip something silly my friend said on discord without me being muted.

Best Regards,
Bernardo.
