For fun i just ran a quick test function, trying to understand where the frustration comes from.

Another option i realized you can use is the “evaluate expression”.

That opens a window and allows you to execute code in that session of that context. Is that what you were looking for?

You should be getting the error from the debugger in the terminal or julia repl depending on what you used. and files in there are clickable (with inline location) via ctrl+click. Otherwise there’d be no crash. I do not get more info than the debgger provides though…
