Hi Harshul
Greetings
Thank you for posting in Microsoft Community.
Please try to access your browser when in a private window this can be done by navigating to your browser menu and selecting either inprivate or incognito window.
Another suggestion would be to change your network, if you're using wifi you may try to use a hotspot to see if the teams page still won't load.
Please feel free to let me know how it goes.
Kind Regards,
Momo
