Safari not loading results/ searches or websites

I am running on a MacBook Air 2017 version with the latest MacOS that is [Big Sur 11.3.1]. From the last 2 weeks, Safari has been giving me issues related to not loading anything that I search ! It takes an eternity to load even the simplest of searches. For eg:- if I just search " news, or hello!, or Batman ". The loading bar just stops completing only 1/4th of its path, and it take around 15-20 seconds for a single simple search, sometimes not even THAT, it just freezes.

My internet connection gives me a constant 200mbps upload and download speed, which is pretty fast, I am able to go full HD on any other device without any loss in ping. In Fact, I can even watch YouTube and netflix on this Mac on HD, but the problem is with loading searches and websites. I have tried clearing all of my history, emptying my entire cache, emptying every other storage of websites and cookies. Basically resetting everything. I have tried steps that numerous websites told me to follow like:

But nothing seems to be working out. I am a safari user, and I believe it's been designed to work perfectly with Macs and its optimised blah blah.... The last option I am left with, is resetting my entire Mac, which I will NOT do. If anyone, please if anyone has got any suggestion as to how to fix this horrible bug, please HELP!
