Lenovo Carbon Gen 13 External Cameras Freeze while using Teams issue on Windows 11

Garcia, Alfredo 30

It seems like many Users are having issues with external cameras freezing on Lenovo Carbon Gen 13s. The model most used is Brio camera but the issue happens with any camera. All Windows Update are installed and all Lenovo drivers and updates are installed but they don't seem to help. Tested with Zoom and Webex and no issues there only appears to be with Teams.

Seems to be an issue with the latest Lenovos.

We have got a handful of X1 2-in-1 Gen 10's which have the same firmware as the X1 Carbon Gen 13's. If you haven't already, raise a ticket with Lenovo. Hopefully we can get more visibility and a fix

We have been experiencing same issue on all X1 Carbon gen 13 and X1 2in1 G10 laptops for months. It seems to affect new Intel Lunar Lake processors, we tested different cameras, different docks, driver updates etc. without any success.

After weeks of troubleshooting we believe we have found the culprit.
It seems to be Lenovo View and Lenovo Aware services.
Digging through the logs I've noticed multiple executables running from \PROGRAMDATA\LENOVO\LENOVOVIEW\ folder matching timestamp of the camera freeze.

To test the theory, I've created a local AppLocker rule to block all executables in %OSDRIVE%\PROGRAMDATA\LENOVO\LENOVOVIEW* ran the test and no more freezes for over hour. Before we were able to replicate webcam freeze every time after 15-30minutes on the call.
We ran the test 3 more times an hour each and no more webcam freezes.

I've asked our support team to test this workaround for most problematic users to get the final confirmation before applying it on all devices via GPO.

Will be reporting all the findings to Lenovo, but until then hopefully this will help to ease the frustration for some of you.

Answer 1

Thanks to Kernius, who seems to have found the root cause.

We found a way that also works, and is hopefully an easier solution for some (we don't use applocker here, so it was hell trying to sort it on my test machine)

Open PowerShell with Administrator Privileges.
Run the following command to determine the OEM number of the Lenovo View Driver: pnputil /enum-drivers | Select-String "lnvvsndmft" -Context 5 Note: If the command does not output anything, the driver is not installed or already deleted.
From the result, you may see a line like "Published Name: oem123.inf" above the line "Original Name: lnvvsndmft.inf".
Please take note of the oemXXX.inf number.
Run the following command to uninstall the Lenovo View Driver completely: pnputil /delete-driver oem123.inf /uninstall /force Note: oem123.inf may differ from what is shown in Step 3.
Restart the system.

Dear Garcia,

Thanks for reaching out to Microsoft Q&A forum support.

From your description, it appears that multiple users are experiencing issues with external cameras freezing on Lenovo ThinkPad Carbon Gen 13 devices. The most commonly affected model is the Logitech Brio, though the issue persists across other camera brands as well. You've confirmed that all Windows Updates and Lenovo system/driver updates have been applied, and the problem seems isolated to the Microsoft Teams app—with Zoom and Webex functioning normally.

To help further isolate the root cause, could you please confirm:

What version of the Microsoft Teams desktop app is currently installed?
Are the users using the classic Teams or the new Teams experience?
Does the issue persist if Teams is accessed via the web browser (teams.microsoft.com) instead of the desktop client?
Are the cameras connected via USB-A or USB-C, and do they go through a dock or hub?

In the meantime, please try the following troubleshooting steps:
Disable GPU Hardware Acceleration in Teams:

Go to Teams Settings > General > Uncheck "Disable hardware acceleration"
Restart Teams and test the camera again

Clear Teams Cache:
- Fully close Teams
- Navigate to %appdata%\Microsoft\Teams via File Explorer and delete all contents
- Restart Teams
Try Teams Web App:
- Visit https://teams.microsoft.com and test if the freezing occurs there (This can help determine if the issue is specific to the desktop client.)
Create a Test Profile:
- Try logging into Windows with a new user profile and test the camera with Teams to rule out profile corruption
Update or Roll Back Camera Driver (if not already tried):
- Open Device Manager > Locate camera > Right-click > Update driver
- If issue started recently, try “Roll back driver” if the option is available

Let us know the results of the above steps and the additional details mentioned so we can better assist you.

Best regards,

The company I work for is now purchasing 13" Gen Lenovo ThinkPad X1 Carbons. All are experiencing this issue with external webcams and Teams.

This just looks like an AI copy/paste response.

Teams removed the GPU Acceleration toggle in "New Teams"

Why would creating a test profile work if it affects many users and not isolated to a single user?
