MS Teams crashes when EOS Webcam Utility is used for Video

Hi, 

I am using Microsoft Teams for my school. I am using EOS Webcam Utility (NOT Beta) with my Canon EOS 80D. It was working perfectly with video calls for school up until about two weeks ago. Now, whenever I turn on my camera in a video call (and the video setting is EOS Webcam), my Teams crashes and I get an error saying, "There was a glitch. Sorry for the inconvenience. Please sign in again." 

In my school, there is an expectation that my camera is on, and my computer's webcam is unusable, so I really need this fixed, and quickly.

Thank you so much for any help you can provide. 

Kane

    Interesting. Lucky you that it works after you join... no matter what I do, even if I am in a call already, if I turn on my camera (or switch over from my fractured webcam, which works but the image is distorted), Teams goes down and I get an error message saying something like, "There was a glitch. Restarting...".

    I have the same issue. It was working up until this week. I was away last week so it also may have stopped working then.

    There are significant UI updates to Teams, including a new UI for device settings when you launch a call, since it was working so I believe the latest update broke it.

    I have found if I select a different camera to start the meeting and then switch to the EOS camera after I have joined it will work.

    It also works if I use OBS as a webcam and then select the OBS webcam—this keeps the EOS camera on regardless of what Teams does.

    I suspect the issue is in how it previews when joining a meeting. Teams tries to enable and disable the webcam 2-3 times during this process and the EOS utility is slow to turn on (particularly since I have a DSLR and the mirror switches every time). 

    The same cycling on/off process happens with all in Teams for me webcams, but it only crashes the EOS Utility camera.

    Hi Kane,

    I'm Nik, an independent advisor here to assist you with this issue.

    Firstly, I would suggest you follow the below basic troubleshooting to avoid common issues due to app cache:

    1. Manually restart the app by right-clicking the icon in your dock (Mac) or taskbar (Windows) and selecting Quit. After you quit, click the app icon to open it again.
    2. Go to File Explorer, delete any of the files in the following locations:

    • %AppData%\Microsoft\teams\application cache\cache

    • %AppData%\Microsoft\teams\blob_storage

    • %AppData%\Microsoft\teams\databases

    • %AppData%\Microsoft\teams\cache

    • %AppData%\Microsoft\teams\gpucache

    • %AppData%\Microsoft\teams\Indexeddb

    • %AppData%\Microsoft\teams\Local Storage

    • %AppData%\Microsoft\teams\tmp

    Also, If the above method still not working. To determine if this user's teams client issue, we would like him to try to login https://teams.microsoft.com/ and see how it works.

    Regards

    Nik
