macos – Safari is super slow at everything even after clear cache

I am having an issue with Safari on macOS that it is super slow at everything, from boot up to new tab to create a new window.
Even with only a single tab, it takes between 45 seconds and 1 minute and 20 seconds to start Safari. Creating a new tab or window takes between 30 seconds and 1 minute. I timed this and I have been able to identify why.
I have done the following:

  • Disabled all extensions (I only had Grammarly)
  • Cleared cache
  • Cleared history and cleared cache

But the issue persists, any ideas why this is happening and how to fix it? The issue started about 3 months ago, but I do not recall an update.
