VSCode running Python Azure Function locally fails with ModuleNotFoundError

Question

I am running VSCode 1.40.0 upgraded very recently on macOS 10.14.6, with Python 3.6.5 in a venv. Prior to the upgrade, my code was working (week before last, the last time I did some work on it). This workspace is a set of Azure Functions, with the following launch.json configuration for running it:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach to Python Functions",
      "type": "python",
      "request": "attach",
      "port": 9091,
      "preLaunchTask": "func: host start",
      "logToFile": true,
    }
  ]
}

The directory structure is:

.
-- env (python env)
-- SharedCode
---- FunctionApp.py
-- TLoginEvents
---- tlogins.py

When I run the code in VSCode, I get the following ModuleNotFoundError:

[11/13/19 5:17:08 PM] Executed 'Functions.TLoginEvents' (Failed, Id=c6e6b342-4250-4041-8d19-8ce4ae8bb736)

Though I never noticed it before, I do find it quite curious that the stack trace seems to be looking into the env for a different project (Data Pipeline) than the one I'm actually running. The current project (Azure Functions) was created by copying the original directory wholesale, but I thought the whole point of the env was that it was local... (I'm still relatively new to Python & VSCode, so if anyone can explain that one, or point me at something that does, I'd appreciate it).

That said, I don't think that's really the issue. If I run python3 in the same env in the Terminal window (even inside VSCode), I can run the import just fine, like so (this is in a stand-alone terminal window):

Dylans-iMac:Azure Functions dylankaufman$ source ./env/bin/activate
(env) Dylans-iMac:Azure Functions dylankaufman$ python3
Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 05:52:31)

>>> from SharedCode import FunctionApp
>>> import datetime
>>> app = FunctionApp.FunctionApp('test', datetime.datetime.utcnow())
>>> app.functionName
'test'
>>> 

In case it is useful, here is the vscode settings.json:

{
  "python.pythonPath": "${workspacefolder}/env/bin/python",
  "azureFunctions.projectRuntime": "~2",
  "azureFunctions.projectLanguage": "Python",
  "azureFunctions.templateFilter": "Verified",
  "azureFunctions.deploySubpath": "Azure Functions.zip",
  "azureFunctions.preDeployTask": "func: pack --build-native-deps",
  "files.exclude": {
    "obj": true,
    "bin": true
  },
  "azureFunctions.pythonVenv": "env",
  "debug.internalConsoleOptions": "neverOpen"
}

(note that I added ${workspacefolder} today as part of troubleshooting this, to no avail)

Thank you for any help/insight you can provide!
