Safari 13.1 "A problem repeatedly occurred"

This is definitely from the recent macOS Safari 13.1 update. Apple should pull this update or at least warn everyone that it's a Safari Browser breaker. I have visited several sites (including my Physician's) and forms are just NOT working. At a time when we are filling out more forms than ever, this is VERY bad timing. Firefox is the fix. Really?

Backup the computer.

Reinstall macOS from macOS Recovery.

Command (⌘)-R

Reinstall the latest macOS that was installed on your Mac (recommended).

If you reload OS, you then will be prompted to update OS, this will put the same version of Safari unless you be selective of the updates that are listed. Don't select update all! I have tried twice. Funny thing is my macbook air same OS, same Safari version, works fine. ?

thanks, have just got off a support call with apple and they tried a few diagnostic things, including creating a new user to see if that also had the problem and loading in safe mode and retrying, problem still occurred in all cases. finally advised backing up and reloading the o/s. I ran a security update today and the problem only occurred after that so I am a little suspicious of that and the more people that post the same error the more I am inclined to think to was that?

I have this problem too, occurred today I'm running 13.1 on Mojave 10.14.6, its driving me mad as it seems to have affected a lot of common websites i use including internet banking and my work training courses, hopefully someone from Apple is looking at this?!

You don't need to wipe HD/SSD

Apple needs to fix/patch this pronto! Not acceptable! April 1, 2020--This is not an April fools thing...I hope.
