Windows 11 is definitely a step up from the old Windows 10, especially when it comes to design, but Microsoft wants us to think that it also excels in the communication department.
Unfortunately, it’s not all fun and games as some of our readers reported that Microsoft Teams is not working in Windows 11.

It seems that Teams is just not opening, or it crashes repeatedly while the widgets window shows multiple instances of the app.
We’ve seen many errors with the program already so it’s no surprise that they also keep popping up in Windows 11.
What are the possible reasons for Teams not working?
Like with any Windows app, Teams can freeze, crash or simply not load and there are a lot of possible causes for that behavior, but we will try to outline the main ones.
➡ Connection problems
The problems with your local Internet connection or the server are probably the most often encountered issues that prevent you from using Microsoft Teams.
So, check if your connection is stable, then try to open the app’s dedicated website and see if they don’t have any announcements about certain server issues.

You can also visit DownDetector and check if other users have reported connection problems with the software at that moment.
➡ Application and system updates
Like with any other app, a lot of issues can appear if you don’t install its latest updates. And we’re also talking about OS updates because the problems can also be linked to that.
➡ File corruption
If you experience any electrical outage, hard drive failures, software conflicts, and other such events, there are chances to get file corruption problems with any app, not just Microsoft Teams.
Another file corruption reason can be malware and virus infections so it’s very important to organize your defense against these threats.
What can I do if Microsoft Teams is not working?
1. Update the app




If you already checked that there are no issues with your local connection or with the server, the first thing to do is to check if you have the latest update for your software.
2. Check for Windows updates


3. Disable and re-enable the graphics driver



Some of our readers reported that disabling and re-enabling the Intel UHD Graphics driver solved the problem for them, but you can try that with any other graphics driver.
4. Try using the online platform


If Microsoft Teams works fine online, then the problem is the desktop application so proceed with the next step to troubleshoot the app.
5. Delete the app’s cache
%appdata%\Microsoft\teams


After this procedure, try opening Teams again and see if it works as it should. If not, move to the next step and use the troubleshooting option in Windows 11.
6. Use the dedicated troubleshooter




7. Repair and reset the app





If resetting the app still didn’t fix the problem, unfortunately, there is one more solution, to uninstall and reinstall the software as shown in the next step.
8. Uninstall and reinstall Teams
