Teams completely freezes after clicking on Contacts.

Hello,

Is anyone else experiencing an issue when clicking on Contacts in the Teams desktop client?

The Contacts section works without any problems in Teams Web, but not in the desktop application.

Thank you in advance for your feedback.

    Microsoft confirmed that it's a bug and they prepare a fix:

    I have the same issue.  I have restored, repaired and re-installed Teams.  These steps did not fix the issue for me.

    I would focus on the local Teams desktop cache and client version. First quit Teams completely from the system tray, then restart Windows and update Teams from the app menu or Microsoft Store if that version is Store-managed. If it still freezes only on Contacts, reset the Teams app from Windows Settings > Apps > Installed apps > Microsoft Teams > Advanced options > Repair, then try Reset if Repair does not help. Also test with the new Teams client profile after signing out and back in. If your organization manages Teams, send the admin the Teams version, Windows build, and confirmation that web works while desktop freezes.

    Contacts works in Teams on the web but freezes the Windows desktop client, so the account data and service are probably available; the failure is more likely in local Teams state or WebView. First update Teams and Windows, fully quit Teams from the system tray, and restart the computer. In Windows Settings, open Apps, Installed apps, Microsoft Teams, Advanced options, and select Repair. If Contacts still freezes, select Reset, understanding that you may need to sign in again. Reopen Teams and test Contacts before restoring optional add-ins or customizations. If the problem remains, uninstall Teams, restart, and install the current Microsoft client. Reproduce the freeze once, then immediately collect support files from the Teams tray menu or with Ctrl+Alt+Shift+1. Record the UTC time and client version. A Teams administrator can compare Client health and submit those logs to Microsoft Support; deleting cloud contacts should not be necessary.
