Upgrade to macOS Catalina broke the Arduino IDE

Everything was working fine and then I upgraded to macOS Catalina. The Arduino IDE version 1.8.12 just wouldn't start. Then I ran from terminal and looked at the actually error.

After some digging around, trying a few things I came across this article https://github.com/arduino/Arduino/issues/9828 and I decided to live life on the edge and try the hourly build! And that did it. So there's an issue and it apparently is known and has been fixed.
