I get the following error every time I start up VSCode:

The mypy server crashed 5 times in the last 3 minutes. The server will not be restarted.

I created a python 3.8 venv and started a project with poetry. I am using the default Microsoft Python language server in VSCode. I have the following setup:

settings.json

"mypy.configFile": "${workspaceFolder}\\mypi.ini",
"mypy.executable": "${workspaceFolder}\\.venv\\Scripts\\mypy.exe",
"mypy.targets": [
    ".",
    "${workspaceFolder}"
],
"python.linting.mypyEnabled": true,
"python.linting.mypyPath": "${workspaceFolder}\\.venv\\Scripts\\mypy.exe",

mypy.ini

Not quite sure what is causing mypy to crash. Can you try changing mypy.targets to just .? You have also ${workspaceFolder} in there, delete that.

Hi @adam-grant-hendry, is the issue still relevant?
