The same code runs fine in vs code directly, if debug often gets stuck and prints an error message after aborting:

I have the debugger crash regularly, but I can’t seem to come up with a MWE. It’s always in reasonable complex code based, and I can’t untangle what’s going on.

Are you able to share Julia version, VSCode version, Julia VSCode extension version, and operating system? Can you find a reasonably small chunk of code that causes the crash when debugged?

Sorry, it maybe not a problem… it’s just too slow under dubugb mode…
