iOS Safari freezes when I type something specific in address bar

Over the past week or so, I’ve noticed that Safari freezes on my iPhone whenever I type the letters “sa” into the address bar. I’ve cleared my cache, I’ve turned the phone off and on, but it’s still doing it. If I type letters before “sa” it will let me type the “sa” but if I then delete all of the other letters, it freezes the moment it’s back to being just “sa”. Any idea what could be causing it?
