One week ago was the December 42.12 release. Open a TAC case and make them identify the bug. In the meantime they may need to help you roll back to 42.11 if a fix cannot be readily identified.

Hello Opale Solutions,

This issue may occur due to high resource consumption. Examples like: Excessive usage of Ram/Processor causes the machine to freeze or crash.

Here are the Troubleshooting Tips:

1. Is your device compliant with the Webex system requirements?
2. Can the issue be replicated while using the Web App? Get started with the Webex Meetings web app.
3. Uninstall the meeting application. Run the Meeting Services Removal Tool or Mac Cisco Webex Uninstaller.
   • Manually download the Meeting / Event / Training application from the site where the user is trying to start or join the meeting. Open your Webex site URL (example: SITENAME.webex.com) and go to Download.

• Contact local IT for assistance if the user needs administrative privileges to install the program.

1. Try on a separate device connected to the same network.
   • If the problem happens on another device, try a different platform on the same network (for example, macOS, Windows 10/11, mobile OS).
   • Try it on a different network (for example, connect your device to a mobile hotspot or router).
     • If the problem is network-related, contact your local IT and share these articles: WBX264 / WBX000028782.
2. Check that your graphic, camera, and audio drivers are all up to date: Cisco Webex and 3rd Party Support Utilities.

• Contact your local IT department or the computer manufacturer for assistance in upgrading the drivers.
• Check if any security software is installed on the machine that is creating this problem.
  • Whether feasible, deactivate it momentarily to see if the problem remains.
