Cannot add google account
I did a clean reinstall to my macbook today but after that I cannot add my google account back. It tells me that google need to open safari to verify the authentication. Click the button "open safari", it opens safari and nothing else happens, just OPEN THE SAFARI ALONE. And the button grays out, what I can do is just click cancel. I am getting mad of it already, please help. By the way it's macOS 10.14.6 and safari 13.0
