Fix 1. Reinstall Microsoft Teams

Reinstalling Microsoft Teams can fix the error by replacing corrupted or missing files and ensuring the software is correctly installed. This is also especially true if you have two versions of Teams installed. Remove both of them and then install a clean one.

• Type Control Panel in Windows search and press Enter.

• Find Microsoft Teams, right-click, and select Uninstall.
• Follow the prompts to remove the app.
• Once done, press Win + E to open File Explorer.
• In the View tab at the top of the window, enable Hidden Files.
• Go to C:\Program Files\WindowsApps location.
• Scroll down to find the Microsoft Teams folder and delete it (alternatively, you can rename it).
• Now type %AppData% in Windows search and press Enter.
• Delete the Teams folder here.
• Finally, restart your system and reinstall the app.

Fix 2. Update Teams

Updating Microsoft Teams ensures you have the latest features and bug fixes. This can resolve compatibility issues and errors caused by outdated software.

• Open Microsoft Teams.
• Click on the Settings and more button at the top-right corner.
• Select Check for updates.
• Teams will automatically download and install any available updates.
• Restart Teams after the update is completed.

Fix 3. Repair or reset Microsoft Teams

Repairing the installation can fix issues related to corrupted files without uninstalling the software.

• Click on Start and pick Settings.
• Go to the Apps section.
• Locate Microsoft Teams from the list.
• Click on the three vertical dots and pick Advanced options.
• Click Terminate to ensure that the app is not running.

Fix 4. Run SFC and DISM

Running System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) scans can repair corrupted system files, which might be causing the error.

  Dism /Online /Cleanup-Image /CheckHealth
  Dism /Online /Cleanup-Image /ScanHealth
  Dism /Online /Cleanup-Image /RestoreHealth
  (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
  
• Close down the Command Prompt and restart your computer.

Keeping your operating system up-to-date can resolve compatibility issues and errors. Regular updates often include patches for known issues.

Fix 6. Clean boot Windows

Performing a clean boot can help identify and eliminate conflicts caused by third-party software. This can isolate the cause of the error.

• Type msconfig in the Windows search box and press Enter.
• Pick the Services tab.
• Mark Hide all Microsoft services and select Disable all.
• Select the Startup tab and click Open Task Manager.
• In the Task Manager, right-click on each of the items and select Disable, then close the Task Manager.
