I’m wondering if this has been seen? Thanks

macOS 13.3beta+UI Browser 3.0.2

Safari Toolbar scan by UI Browser does not cause crash for me.

Please see my steps above

You need to use follow focus, then click on a Safari toolbar. Then you’ll see a crash.

I see. After 10 toolbar button clicking, UI Browser 3.0.2 crashed.

I use UI Browser from the first release version. I forgot the existence of the function.
Because I decided not to use the function because of crash.
