Can't open files from Teams in Office desktop app

I've been using MS Teams to work with PowerPoint and Excel documents with the option Open in desktop app. Until a few weeks ago  when I try to open a document with the option open desktop app I get the launching window of the app (any office app like Excel, Powr Point, Word, etc.) but it doesn't start anything. This is with all the files I try. I haven't made changes to my settings or anything. I have tried to clear the cache in the Teams Folder and I have checked that the apps are linked to the right file types but nothing works. I also have looked on the official site for help and in this community but I can't find any fixes that solve this.

    Hi Dave,

    Since the issue persists, I'd like to check if it also happens to Teams web client. If so, you can try to collect the Teams log file by using the web debug tool.

    1. Open a single web page in browser's private mode and sign in Teams web client.
    2. After the web page is completely loaded, press F12 to open web debug tool, then navigate to Network tab.
    3. Click the button to start capturing the HTTP traffics, then reproduce this issue. You can reproduce this issue 2~3 times.
    4. Stop capturing the traffics, then export as har file and send to us via Private Message.

    While if the issue doesn't happen in Teams web client, please open Teams desktop client and press Ctrl + Shift + Alt + 1 to download the Teams diagnostic log and send to us in Private Message. The diagnostic log will be downloaded to Downloads folder.

    Regards,

    Marvin

    Hi Dave,

    Sorry for the late reply. I've checked your log file and found there's a 404 error when it tries to launch Office app. HTTP 404 generally indicates the object is not found. So I think this issue is related with the process when Teams tries to open the other Office applications. I'll try to consult our senior engineering team for this issue. And if it's convenience, please also collect Teams diagnostic log (Ctrl + Shift + Alt + !) for us.

    Besides, may I know your Office app version? Please open Word app and capture a screenshot via File > Account > Product Information for us.

    Regards,

    Marvin

    I recently started having the same issue. When I go to Settings**> Apps & features > Default apps >**Choose default apps by protocol there is no default app for word or excel. When I select choose default app, Im told there is no app and directed to Microsoft store to purchase.
