The insider hub needs to state if gameplay is allowed to be captured during any game beta's

What worked for me was to leave the beta testing program from the Insiders hub and then reinstall the game. My girlfriend just needed to update it after leaving. Do check the Insiders Hub to see if you're participating in the beta testing, still.

This may well be a game related issue, if you aren't seeing it on any other games. You can download the Xbox Insider Hub app (you do not need to sign up to the preview program) and at the point where this happens, file a report, allowing video and screen
shot captures to be attached. This will send the relevant data to the team, who can then pass it on to the game developer.

Yes I'm in insider hub program but I'm new member and have

access only for Omega Update and we need Delta or Beta Updates to fix this 4K Capture issue .

Please give us regular update with fix for that issue.

Thank you

W aplikacji "Insider Hub", trzeba nacisnąc "Insider Content", pózniej nacisnąc "Minecraft beta" I tam można się odrejestrować

[Mod Translation - In the "Insider Hub" application, you need to press "Insider Content", then press "Minecraft beta" and there you can unregister]

Have you downloaded the Xbox insider hub app? I believe that update is still in beta. So to download it, you will need to go to the xbox store and down load the Xbox Insider Hub.

Hope this helps, Happy Gaming!!!
