I had a similar issue and I believe it was created by using virtualenv and having my .venv folder being loaded by VSCode. I added the following to my .vscode/settings.json and it fixed it:

  "files.exclude": {
    "**/.git": true,
    "**/.svn": true,
    "**/.hg": true,
    "**/CVS": true,
    "**/.DS_Store": true,
    "**/*.pyc": true,
    "**/__pycache__": true,
    ".docker/**": true,
    "**/.serverless/**": true,
    "**/.venv/**": true,
    "**/.ipynb_checkpoints/**": true,
    "**/.pytest_cache/**": true,
    "**/node_modules/**": true,
  }

The important part is "**/.venv/**": true,
