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

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

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

  1. Open Microsoft Teams, click on the three dots button, then select Update Teams and restart.
  2. If you can’t see the update option, click on the three dots button and select Settings from the menu.
  3. Now click on About Teams.
  4. If there are any new updates for teams, they will appear under the version section. You can also check the version number with the latest one from the Teams website and see if you have the newest.

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

  1. Click the Start button, then select Settings.
  2. Select Windows Update from the left pane and click the Check for updates button .
  3. If there are any new ones, the system will download and install them and after that, you will be prompted for a restart.

3. Disable and re-enable the graphics driver

  1. Click the Search icon on your Taskbar, type device manager, and click on the app from the results.
  2. Select the Display adapters section to expand it right click the driver and select Disabel device.
  3. After you accept the procedure, right-click the driver again and select Enable device.

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

  1. Instead of using the desktop app, open the dedicated Teams website and click on the Sign in button.
  2. Enter your credentials and hit the Singn in button.

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

  1. Press the Windows key + E to start File Explorer, then paste the following path in the navigation tab and press Enter: %appdata%\Microsoft\teams
  2. Delete all the contents from the following folders: blob_storage, Cache, databases, GPUCache, LocalStorage, and tmp.

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

  1. Select the Start button and choose Settings.
  2. Make sure you select the System section from the left, then scroll down in the right pane, and click on Troubleshoot.

  5. After the repair process is finished and you see a checkmark, try to open the app again. If it’s still not working, click the Reset button but keep in mind that all the app data will be deleted.
