How to Fix Microsoft Teams Crashing on Windows 11 and 10

Microsoft Teams is one of the many pre-installed apps in Windows 11. Unfortunately, while it is an excellent business collaboration platform, it is plagued by the occasional crashing issues.

If the Microsoft Teams app is crashing or keeps restarting on your PC, here is how to troubleshoot and fix the problem in Windows 11 systems.

1. End the Microsoft Teams Process in Task Manager

How to Fix Microsoft Teams Crashing on Windows 11 and 10

Press Win + R to open the Run dialog.
Type taskmgr and click OK to open the Task Manager.
In the Process tab, look for any tasks associated with Microsoft Teams.
Select the process and click End task.
Close Task Manager and launch the Microsoft Teams app. Check if the app works without crashing.

If the problem persists, perform a restart. A quick restart will force end all the background processes and help resolve issues due to temporary glitches.

2. Repair Microsoft Teams

You can repair some Microsoft Store apps and programs in Windows 11 and the older version of OS. The repair feature tries to repair the installation, thus fixing any problems triggered due to file corruption.

To repair the Microsoft Teams app:

Press Win + X to open the WinX menu.
Click on Settings from the context menu.
Open the Apps tab in the left pane.
Click on Apps & features.
Locate or search for the Microsoft Teams app. Then, click the three-dots menu next to the app name and select Advanced options.
Scroll down to the Reset section and click on Repair. Windows will start repairing the app and show a checkmark after the repair is complete.
Close the Settings page and launch Microsoft Teams to see if the crashing problem is resolved.

3. Clear Microsoft Teams Cache with App Reset

Like other Windows apps, Microsoft Teams uses cache space to store temporary files to improve the load time and user experience. But when not used properly or corrupted, it can cause the app to malfunction.

You can manually clear the app cache to resolve this problem. Here’s how to do it for Microsoft Teams.

Open the Settings page.
Click on the Apps tab in the left pane.
Next, go to Apps and features.
Locate the Microsoft Teams app and click the three-dots menu.
Select Advanced options.
Click the Reset button. Then, click Reset again to confirm the action.

The reset process will restore the app to its factory default deleting all the data, including cache. However, it will also delete any saved login credentials. So, you will need to log in again to use the app.

4. Update the Microsoft Teams App

Newer updates often include bug fixes and performance improvements. While Microsoft Teams auto-updates every two weeks, you can manually check for a newer update in the app settings.

To update Microsoft Teams:

Launch the Microsoft Teams app.
Click the three-dots (Settings and more) in the top right corner and select Settings.
Open the About Teams tab in the bottom left corner.
Microsoft Teams will check for pending updates and install them if available.

5. Update the Display Adapter Driver

Incompatible Intel HD graphics drivers are another known cause for the Microsoft Teams crashing issue. If you have the Intel HD graphics installed, update it using the Device Manager to fix the problem.

To update the display adapter driver:

Press the Win + R to open Run.
Type devmgmt.msc and click OK to open Device Manager.
In Device Manager, expand the Display adapters section.
Right-click on Intel HD Graphics device and select Update Drive
Select Search automatically for drivers. Windows will now look for the newer version of the drivers and install them automatically.

If no update is found, go to Intel's Drivers & Software page. Open the Graphics section and download the latest version of the drivers available for your processor.

6. Disable the Display Adapter Driver

If updating the display driver did not help, uninstall the graphics driver to see if that helps you resolve the error. When uninstalled, Windows will use the generic display driver, but it will help you determine the cause of the problem.

To uninstall the graphics driver:

Press Win + X to open the WinX menu. Then, click on Device Manager.
In Device Manager, expand the Display Adapters section.
Right-click on the Intel HD Graphics device driver and select Disable device. Click Yes to confirm the action.
Next, right-click on the display adapter and select Enable.

7. Reinstall Microsoft Teams

As a last resort, you can reinstall the Microsoft Teams app to fix the crashing problems. A quick reinstall can help you fix problems caused due to app file corruption and other reasons.

To uninstall Microsoft Teams:

Go to Settings > Apps > Apps & features.
Locate the Microsoft Teams app and click the three-dots menu next to the app name.
Select Uninstall. Then, click Uninstall to confirm the action and uninstall the app.
Next, open the Microsoft Teams download page.
Select your Windows version and click the Download button.
Run the download package and install the app.

8. Run the System File Checker Tool

If Microsoft Teams fails to launch, you can run the System File Checker tool. It will scan the system for file corruption and restore the corrupted system files. This is helpful if the system-related issues are preventing the app from launching.

Press Win + X to open the WinX menu.
Click on Windows Terminal (Admin).
In the Terminal window, type the following command and press enter:
```
sfc /scannow
```
Depending on your disk drive size, the process will take a while to complete. Once completed, it shows a summary of the errors found and fixed.
Restart your PC and launch the Microsoft Teams app to see if it works normally.

Fixing the Microsoft Teams App Crashing Problem

Often the built-in troubleshooter can diagnose and fix problems causing the Microsoft Teams app to crash. If not, try updating your display adapter drivers or reinstalling the app.

While Microsoft Teams is an excellent team collaboration app, it’s not the only choice. There are plenty of great Microsoft Teams alternatives, with Slack being an equally popular choice.
