Steam Link / Streaming: Game doesn't detect controller on Windows 11 24H2

[QuadPro]

I have an Apple TV device on which I have the Steam Link app installed. My wireless Xbox controller is connected via Bluetooth to the Apple TV. Games are installed on my Win 11 desktop PC. Streaming the desktop PC to the Apple TV using Steam Link used to work perfectly.

Since upgrading my PC to Win 11 24H2 , when streaming a game to my Apple TV the games no longer detect the controller. The strange thing is that the controller does work on the Steam interface, and it also works when I put the controller in Mouse mode.

Anyone familiar with this problem who is able to help?

Just tried with a laptop connected to my TV, acting as a streaming client. Same problem: streamed games do not recognize the controller, while I *can* use the controller to control the remote session itself, and mouse mode works as well.

I have the same problem, I'm trying to connect my phone, my laptop, and my Chromecast but it's impossible. Windows 11 doesn't recognize my GamerSir controller or even the touch controller of Steam Link. Ultimately, I preferred to go back to Windows 10 21H2 and the problem was solved, but now the Xbox app says it's not compatible with my Windows system...
Please, if the problem is solved in any update of Windows 11 or Steam, or something is found that fixes it, you can let me know here so I can update to Windows 11 again.

I updated to the Steam Beta (version 1730416762) and I'm happy to see that the problem no longer occurs! I tested it on two Windows PCs and updated both the client and the server Steam installations. I haven't yet tested streaming to the Steam Link app on my Apple TV though, but I'm hopeful that'll work as well.
