Microsoft has introduced trust-based enhancements to the Teams Admin Center (TAC), designed to simplify app security and compliance management for IT administrators. These updates, known as Trust Through Certification, enable you to quickly identify trusted applications, enforce organizational standards, and streamline governance workflows through features such as "apps to consider allowing," security compliance filters, and Microsoft-certified app collections.

1. Press Windows + R to launch the Run dialog.
2. Type the command below and hit Enter.
%appdata%\Microsoft\Teams
3. Delete the folder’s content and try to start Teams to see if the problem is fixed.
Fix 3: Force Close Microsoft teams in the Task Manager
If you are having problems opening Teams, there is a chance that a Teams process is already running. To fix the problem, you will have to close this in the Task Manager. You may have to pause Task Manager updates to complete this process.
1. Press Ctrl + Shift + Esc to open the Task Manager.
2. Search for Microsoft Teams, right-click it, and click End task.
Fix 4: Repair and Reset Microsoft Teams
many native Windows 11 applications come with built-in Repair and Reset features. These features will scan for problems within the app and also take the app to its default settings. Follow the steps below to repair and reset Teams when it is not working.
1. Press Windows + I to open the Windows 11 Settings app.
2. Click Apps on the left pane, then click Installed Apps on the right.
3. Click the 3 dots for Microsoft Teams, then click Advanced options.
