Linter crashes when run via VS Code

[debonte]

Perflint works on the command line against the file below, but crashes when run via VS Code.

Here's the command line output:

>perflint src\CursesRenderer.py
************* Module CursesRenderer
src\CursesRenderer.py:57:46: W8201: Consider moving this expression outside of the loop. (loop-invariant-statement)

-----------------------------------
Your code has been rated at 9.75/10

And here's the output I see in the Python log when opening the file in VS Code:
