Microsoft Teams relaunching by itself

I'm from an MSP. We have 2 tickets for different customers with the same issue. MS Teams is relaunching by itself. I already cleared the cache, reboot, and reinstalled Teams.

Anyone here knows if there's an ongoing issue? Or if you guys know a fix. Thanks!

    Dear @Thirdy,

    To ensure I understand your request correctly and to support you as effectively as possible, I need more specific information from you:

    • Does it also happen in Teams on the web?
    • What Teams version and OS build are affected?
    • Did it start after a recent update/change?
    • When did this issue happen (while in a meeting, suddenly relaunching)?
    • Does it happen for another user on the same PC?
    • Does it happen on another PC with the same user?
    • How is the process of the tickets?

    Your provided information will help me assist your more promptly and efficiently.

    In the meantime, kindly try these steps:

    1> Using Teams on web

    Please try to use Teams on web and check if it works normally.

    2> Repair or reinstall the WebView2 Runtime

    (This is one of the most common causes of New Teams auto‑restarting.)

    New Teams relies heavily on Microsoft Edge WebView2. If WebView2 is missing, corrupted, or blocked, Teams may close and restart on its own.

    Close Teams completely (right‑click the Teams icon in the system tray > Quit).

    Open Task Manager > end any msedgewebview2.exe processes.

    Download and install the WebView2 Evergreen Standalone Installer (choose x64 or ARM as needed).

    Restart your device.

    If the installer says WebView2 is already installed but Teams continues restarting, please refer to this article: Resolve Teams Client Crash Issues - Microsoft Teams

    I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

    The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

    Based on similar reported cases, there are a few known patterns and workarounds when the Teams desktop app repeatedly crashes and relaunches by itself.

    1. Confirm it’s not a transient client crash
      In one case, the desktop client stabilized after being left open for a while. The user left Teams running for about an hour, then a prompt appeared indicating Teams had encountered a problem and needed to close or proceed. After choosing Close and then granting the requested camera permission, the app stopped crashing and worked normally again. Action: On an affected device, leave Teams open for an extended period (30–60 minutes) without force-closing it, and watch for any crash or permission prompts. If a dialog appears, choose to close/restart as prompted and allow requested permissions.
    2. Check for conflicting software (e.g., Astrill VPN)
      Multiple users reported continuous Teams crash/restart loops after an update, which were resolved by removing the Astrill VPN client:
    • In one case, Teams kept crashing and restarting after updating to a newer version. Removing Astrill immediately resolved the issue.
    • In another case, Teams repeatedly crashed and reloaded; the workaround from a related thread (also tied to Astrill) fixed the behavior. Action:
      • On affected endpoints, check if Astrill or similar VPN/network overlay software is installed.
      • Temporarily uninstall or fully disable Astrill, then restart Windows and test Teams again.
      • If removal fixes the issue, treat Astrill (or the conflicting app) as the root cause and adjust the customer’s standard build accordingly.
    1. Fully remove residual Teams data under AppData
      For persistent crash loops that survived normal uninstall/reinstall and cache clears, one user resolved the issue only after manually deleting all remaining Teams-related files under the entire AppData tree: Action (per device):
      1. Uninstall Microsoft Teams.
      2. Under the user profile, search the entire %AppData% tree (both Roaming and Local) for folders and files containing teams in their name (not just %appdata%\Microsoft\Teams).
      3. Delete all those Teams-related folders/files.
      4. Reboot the machine.
      5. Reinstall Teams from the official source and test again.
    2. Standard connectivity and cache checks
      If the symptom is “Teams opens, shows a blank window, then disappears,” also validate:
    • Network/firewall/proxy allow access to Teams endpoints.
    • Teams cache has been cleared correctly using the documented paths for classic vs. new Teams. Action: Follow the official cache-clear steps for Windows (classic or new Teams) from the documentation, then restart Teams.
    1. If managed via Intune on macOS
      If any affected users are on macOS with Microsoft 365 apps deployed via Intune and apps are closing and then reinstalling silently, check for multiple or misconfigured Required assignments of the Microsoft 365 Apps for macOS suite and adjust as documented.

    If, after these steps, the issue persists across multiple tenants and devices with no common third‑party software, collect crash logs and open a support case with Microsoft, as this may indicate a new client-side regression.
