I tried using different browsers(firefox,edge) but none of them seems to work. I tried disabling my adblocker and extension and that didnt worked either. Is there a way to fix this Problem. Codeforces is the only website which is not working properly all other websites are working fine.

Codeforces is the only website which is not working properly, all other websites are working fine.

It seems that, for whatever reason, an SSL certificate associated with the website has an invalid date and is causing resources to fail to load (because the HTTPS connection to those resources is effectively broken by that invalid SSL certificate):

Failed to load resource: net::ERR_CERT_DATE_INVALID

Is there a way to fix this problem?

If you aren't responsible for Codeforces, then likely no. You can try perhaps clearing your browser caches, etc. and trying to reconnect, but if the website (or perhaps a proxy) is delivering an invalid SSL certificate, there often isn't much that can be done on the user's end.
