Solution 1Recommended

Update System and Test Web Version

Installing the latest updates can patch known bugs causing the application to crash, while testing the web version helps isolate whether the issue is strictly related to the desktop client.

Microsoft frequently releases patches for the Copilot application and Windows OS to resolve stability issues. Ensuring both are up to date is the primary step in troubleshooting unexpected crashes.

1
Close the application

Fully exit the Microsoft Copilot desktop app. If it is frozen, use the Task Manager (Ctrl + Shift + Esc) to end the Copilot process.

2
Install Windows and app updates

Navigate to Windows Settings > Windows Update and install any pending updates. Then, open the Microsoft Store to check for and install updates specifically for the Copilot app.

3
Restart and verify

Restart your computer, launch the Copilot desktop app, and test a conversation to see if the crashing persists.

4
Test the web version

If the desktop app continues to freeze, open your browser and navigate to the web version of Microsoft Copilot. If the web version works perfectly, the issue is isolated to your local desktop installation.

Frequently Asked Questions

Why does my Microsoft Copilot desktop app keep freezing?

Freezing is typically caused by outdated application versions, missing Windows system updates, conflicting background processes, or corrupted local installation files. Keeping both your operating system and the Copilot app updated is the best preventive measure.

Yes. If the desktop client fails or hangs, you can seamlessly continue your work by accessing the web version of Microsoft Copilot through your preferred internet browser.

What information is needed when reporting a Copilot crash to Microsoft?

When creating a support request in the Microsoft 365 Admin Center, corporate admins should provide exact crash timestamps, the scale of affected users, device operating system details, and any available crash logs or diagnostic reports.
