Why is Safari not opening websites on macOS Sequoia?

I just updated my macbook Air M1 to Sequoia couple of days ago. Everything runs well except Safari.

Since then, I cannot open any websites on Safari. No error message, it only shows blank page and the loading meter keeps running but nothing shows up. I cannot even open the Mac support on apple.com. This is so frustrating and disappointing, I prefer to use safari than other browsers.

Anyone experience the same issue?

Anyone can share how to fix this issue?
