How to Fix it when Microsoft Teams Keeps Crashing on Windows 11 or Windows 10 PC

Microsoft Teams is a widely used platform for business communication. However, some users have encountered an issue where the app keeps crashing on their Windows 10 or Windows 11 PCs. If you’re facing this problem, there are several solutions you can try to resolve it. Below are methods ranging from simple to more in-depth steps to help you fix the crashing issue in Microsoft Teams.

Check Microsoft Teams’ Service Status

Before troubleshooting on your device, it’s wise to ensure that the problem isn’t with Microsoft’s servers. If Teams servers are down, the app may crash or fail to open. You can quickly check the service status to confirm.

Open your preferred web browser and go to portal.office.com/servicestatus.

Look for the ‘Teams’ option on the left side of the page. If you see a green tick next to it, the servers are running correctly. Any other symbol indicates an issue with the service.

If the servers are functioning properly, proceed to the next method to troubleshoot the issue on your device.

Kill Microsoft Teams App from the Task Manager

Sometimes, even after closing the app, some of its processes continue to run in the background, preventing it from restarting properly. Terminating all Teams processes can help.

Press Ctrl + Shift + Esc to open the Task Manager. Alternatively, you can right-click the Start Menu and select ‘Task Manager’.

In the Task Manager window, find ‘Microsoft Teams’ in the list of running applications.

Right-click on ‘Microsoft Teams’ and select ‘End Task’ to close all running processes associated with the app.

Restart the Microsoft Teams app to see if the issue has been resolved. If it persists, try the next method.

Clear Microsoft Teams’ Local Cache

A corrupted cache can cause Teams to crash repeatedly. Clearing the local cache can help the app start afresh without any stored errors.

Ensure that Microsoft Teams is completely closed. Check the system tray to confirm that it’s not running in the background.

Press Windows + R to open the Run dialog box. Type %appdata%\Microsoft\Teams and press Enter to navigate to the Teams cache directory.

In the folder that opens, select all files and folders by pressing Ctrl + A. Then, press Shift + Delete to permanently delete them. Confirm any prompts that appear.

Launch Microsoft Teams and check if the crashing issue is resolved.

Repair or Reset Microsoft Teams from the Settings App

If the problem persists, repairing or resetting the app through Windows Settings can fix corrupted files without affecting your data.

Press Windows + I to open the Settings app.

Click on ‘Apps’ from the left-hand menu, then select ‘Apps & features’ on the right.

Scroll down or use the search bar to find ‘Microsoft Teams’. Click the three-dot menu next to it and select ‘Advanced options’.

In the ‘Reset’ section, click on ‘Repair’. Windows will attempt to fix the app without affecting your data.

Once the repair is complete, a checkmark will appear next to the ‘Repair’ button. Open Teams to see if the issue is resolved.

If repairing doesn’t work, you can reset the app. In the same ‘Reset’ section, click ‘Reset’. Be aware that this will delete the app’s data, and you will need to sign in again.

Confirm the reset by clicking ‘Reset’ again in the prompt that appears.

After resetting, launch Teams and sign in to check if the crashing issue has been fixed.

Reinstall the Microsoft Teams App on Your Windows PC

If none of the above methods work, reinstalling Teams can resolve deeper issues by installing a fresh copy of the app.

Open the Settings app by pressing Windows + I.

Navigate to ‘Apps’ and then ‘Apps & features’.

Find ‘Microsoft Teams’ in the list. Click the three-dot menu beside it and choose ‘Uninstall’. Confirm the action when prompted.

Restart your computer to ensure all components are fully removed.

After restarting, click on the ‘Chat’ icon on the taskbar (if available). If you don’t see it, you can download the latest version of Microsoft Teams from the official website.

Click ‘Continue’ to install Teams. If prompted, you can choose to use the same account or sign in with a different one.

Once installation is complete, launch Teams and verify if the crashing problem is resolved.

By following these methods, you should be able to fix the crashing issue with Microsoft Teams on your Windows PC. If the problem continues, consider reaching out to Microsoft Support for further assistance.
