Teams Desktop Client Crashes on Launch for Some Windows Users

Microsoft is investigating an ongoing issue that's causing some Windows users to experience significant delays or outright failures when launching the Microsoft Teams desktop client.

The company acknowledged the problem, tracked internally as TM1466820, and confirmed it remains unresolved as engineers continue digging through service logs to find a root cause.

Affected users encounter trouble specifically during the first launch of Teams on a Windows device. Some cannot load the client at all, while others experience delays stretching up to two minutes before the app becomes usable.

Microsoft has recommended workarounds to keep productivity moving, including switching to Microsoft Teams on the web through a browser or using the Teams mobile app, both of which reportedly remain unaffected by the desktop client's loading problem.
