Mycrosoft Teams stop sharing screen in new version of Edge browser on Linux

I'm writing to report an issue with screen sharing in Microsoft Teams after updating Microsoft Edge to version 131.0.2903.48 (Official build) (64-bit) this morning (18/11/2024).

The Problem:

When attempting to share my screen in Microsoft Teams through the Edge browser, I can only share the browser window itself. Sharing the entire screen or specific applications is not possible.

Additionally, clicking "Share Screen" causes my camera to turn off with an error message stating "Your video isn't working. We couldn't access your camera."

This issue occurs in both the Microsoft Teams web app within Edge and the standalone Teams desktop application (if available on your platform).

Troubleshooting Attempts:

I have verified that screen sharing works flawlessly in Google Chrome on the same system.

A colleague using Ubuntu 24.04 is experiencing the same problem, suggesting the issue is not specific to Ubuntu 22.04.

Possible Cause:

This issue may be related to the recent Edge update or potential compatibility issues with Ubuntu.

Request:

I would appreciate it if you could investigate this issue and provide a possible solution or workaround. Additionally, please consider escalating this issue to the appropriate team if necessary.

    I can second that. No chance to downgrade something when infosec is a big issue for every application.

    Don't want to hijack that issue. But MS has some strange decision making (overall qualitity?) regarding their own browser. For example FIDO2 support missing in edge4linux https://learn.microsoft.com/en-us/entra/identity/authentication/concept-fido2-compatibility

    I did a downgrade of microsoft edge and the screen sharing is working.

    sudo apt --reinstall -y microsoft-edge-stable=130.0.2849.46-1

    apt-mark hold microsoft-edge-stable

    microsoft-edge-stable --version

    Remember to close all opened edge and teams.
    I did a "kill" to be sure
    killall msedge

    I have the same problem. Resolved by rolling back to 130.

    This is good page for testing the problem.
