FIX 7: Disable GPU Hardware Acceleration in Teams

When this feature is enabled, your CPU might shift some o the workload over to the GPU so that it has some additional resources in hand for other applications. However, in some instances, the GPU isn’t able to handle this workload efficiently and ends up doing more harm than good. Therefore, you should consider disabling this functionality, using the instruction given below-

1. Launch Teams and go to its Settings menu.
2. Then select General from the left menu bar.
3. Now check Disable GPU hardware acceleration.
4. Finally, restart Microsoft Teams and check if it is working on your Windows 11 PC or not.

1. Press the Windows+X shortcut keys and select Device Manager from the menu that appears.
2. Then expand the Display Adapter section, right-click on your graphics card, and select Update Drivers.
   
3. Then choose Search automatically for drivers.
   
4. Windows will now search online for the available drivers and would subsequently download and install them.
5. Once done, restart your PC and then check if it fixes Microsoft Teams not working in Windows 11.

FIX 9: Disable Firewall

In some instances, the Windows Firewall might raise a false positive and flag a genuine data exchange process as a malicious one. This in turn will prevent the app [which is Teams in this case] from accessing the internet on your PC. However, if you are sure that the source and destination of the data exchange are trustworthy, then you could temporarily pause the firewall and test out the results. Here’s how it could be done:

1. Head over to the Start menu, search Windows Defender Firewall, and open it.
2. Then click on Turn On/off Windows Defender Firewall from the left menu bar.
   
3. After that, select Turn off under both the Public and Private networks.
   
4. Check if it fixes Microsoft Teams not working in Windows 11.

FIX 10: Use SFC and DISM Commands

System File Checker and Deployment Image Servicing and Management are two command-line utility tools that scan for corrupt Windows files and then replace them with their working counterpart. The major difference between the two is whereas the SFC replaces the corrupt files with the working ones from the cached directory on your PC, DISM does so by downloading the working files from the online Microsoft servers. And as of now, we would be making use of both these tools to fix the underlying mouse issue. Follow along.

1. To begin with, launch CMD as an administrator from the Start Menu.
2. Then execute the below command to open the SFC Tool:

   sfc /scannow

   

3. Once the SFC Scanning is complete, it’s time to use the DISM Tool. So copy-paste the below command:

   DISM /Online /Cleanup-Image /RestoreHealth

   

4. Now restart your PC and check if it fixes the Microsoft Teams not working in Windows 11.

If the app’s data or configuration settings has got corrupted, then it would result in the inability of the app to function along the expected lines.

1. Launch the Settings menu via the Windows+I shortcut.
2. Then go to Apps > Apps and Features > Microsoft Teams.
3. Now click on the overflow icon next to it and select Advanced Options.
4. Then scroll to the Reset section and click on Reset. Wait for the process to complete.
5. Once done, check if it fixes Microsoft Teams not working in Windows 11.

FIX 12: Reinstall Microsoft Teams

If none of the aforementioned methods managed to spell out success, then your last course of action should be to uninstall the app and then reinstall its latest version from the offcial site. [Before uninstalling, make sure to take a backup of all the data and files beforehand].
