Crashes in VS Code

[hakkelt]

Hi,
From time to time, the debugger crashes in VS Code when stepping through lines one by one. I suspect that it might be a timing-related issue because it usually doesn't occur when I keep a couple of seconds between the steps. Here is the error message and the stacktrace:

┌ Error: Some Julia code in the VS Code extension crashed
