Safari keeps freezing on launch & I can't access preferences to clear cache

Hi, I'm on Mac OS 10.15 and having trouble w/ Safari crashing/freezing immediately on launch w/ over a dozen windows opening immediately. Fyi, I had too many windows open at the time my Mac first crashed and so there is a continuous loop of the windows opening immediately after I've *Force Quit*.

Since Safari is "frozen" (just the spinning wheel), I'm unable to go into the app to change things within Preferences.

So, I did the following but nothing changed:

--Clearing via reboot

--Reinstalling the Safari app

--Going into ~/Library/Caches/com.apple.Safari/ and manually clearing from folder

--Running malwarebytes to see if anything was infected from withing the browser. (It wasn't.)

What else can I do?

I look forward to some suggestions.

Thanks,
