Answer 1

This Teams app version 25332.1210.4188.1171 is outdated, as it was released in December last year.

https://learn.microsoft.com/en-us/officeupdates/teams-app-versioning#classic-teams-app-version

You should update this application.

Uninstall any currently installed Teams application and install the current version using this installer site:

https://www.microsoft.com/en-us/microsoft-teams/download-app

In order to avoid any conflict with the locally cached data, reset the local cache before installing the new Teams app.

https://learn.microsoft.com/en-us/troubleshoot/microsoftteams/teams-administration/clear-teams-cache

Be sure to use the option applicable to the New Teams application.

Answer 2

The error you are encountering when trying to open Microsoft Teams may be related to issues with the application itself or its installation. Here are some steps you can take to troubleshoot and resolve the issue:

Check for Reparse Points: Ensure that the Cookies and Cache shell folders do not point to a reparse point. You can run the following PowerShell commands:
```
   (gp ([environment]::getfolderpath("Cookies"))).Attributes -match 'ReparsePoint'
   (gp ([environment]::getfolderpath("InternetCache"))).Attributes -match 'ReparsePoint'
```
If either command returns True, you may need to update the registry entries for those folders.
Permissions Check: Verify that you have the necessary permissions to access the folders in the AppData directory. Make sure that the SYSTEM account and Administrators group have full control permissions.
Clear Cache and Reinstall: Since you've already attempted to clear the cache and reinstall Teams, ensure that you are completely removing all related files before reinstalling. This includes checking for leftover files in the installation directory.
Check for Conflicting Software: Sometimes, third-party applications like VPNs (e.g., Astrill) can interfere with Teams. If you have such software installed, try disabling or uninstalling it to see if that resolves the issue.
Update Windows: Ensure that your Windows operating system is up to date. Sometimes, compatibility issues arise with older versions of Windows.

If the problem persists after trying these steps, you may want to consult the Microsoft Community for further assistance.
