I had the same experience … I correctly entered my site key and secret key in Wordfence and saved. I then logged out of my admin area and tried logging in again.
At login the system told me:
(quote)
VERIFICATION REQUIRED: Additional verification is required for login. Please check the email address associated with the account for a verification link.
(unquote)

I duly received and clicked the “verify and login” link but when I correctly entered my login details, nothing happened — I simply remained on the login page.
I tried this using both Firefox and Chrome on my windows 10 machine with the same result.
I now appear to be permanently locked out of my site!
HOW TO RESOLVE, PLEASE??

Presumably to resolve this issue, I need to follow this procedure … ??

Thanks Dave for the quick response.
I have several sites in the same Litespeed hosting account and find that the crash happens regardless of whether it is an auto-update or manual update.
Seems the only reliable way is to deactivate Wordfence, then delete, then do a new install, then activate … mmmmm … bit tedious …

I experienced the exact same problem with the Custom HTML widget and resolved it simply by installing/activating one of the standard PHP Code Widget plugins…
