    Unfortunately it didn't worked after all suggested trouble shooting.

    I managed to get it working by uninstalling Teams along with Microsoft Visual C++ Redistributable x86 and x64.

    Reinstalled both, restarted computer and reinstalled Teams latest version from web.

    This is the entry you need to perform a repair on or uninstall it and install a fresh installation from

    https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

    But the repair option should fix it. Once repaired, restart the machine.
