Looks like it crashes at 606 (you can nest 605 and it will work).
To be fair, I can’t imagine any situation where you’d have a depth of over 600 in any JSON structure. If so, I’d point to bad design. Regardless, Studio should be able to avoid a crash with this.
Looking into the logs, I see this:
Exception Code: 0xC00000FD
Exception Information: The thread used up its stack.
So I’m assuming that’s a stack-overflow essentially?
Edit: Yeah, this is a stack-overflow error according to this page based on that exception code above.
