In Oct 2022, there was an issue: when you upgrade the macOS to 13.0 Vetura, Katalon Studio crashed.
The reason was that macOS 13.0 had a bug, which affected Katalon Studio (more specifically affected the WebKit, HTML rendering engine, which KS uses to show the Tutorial and QuickStart page).
In order to workaround the macOS’s problem, Katalon team modified Katalon Studio v8.5.3-alpha so that it does not open the Quick Start page and others inside Katalon Studio’s main window.
Later, the macOS was upgraded (13.? I haven’t checked which version) to fix the root cause.
I wonder if Katalon Team has restored their interim code change in Katalon Studio properly.
