Hi Robinson,
I'm Nik, an independent advisor here to assist you with this.
May you please check if you have any available windows update on your laptop? If yes, please apply the latest update and try again.
May I know if you have installed any recent software or any hardware change on your laptop?
Meanwhile, please access MS Teams web app
