ModuleNotFoundError when importing installed module in venv

I installed a library inside a virtual environment using venv in Visual Studio Code, then imported it into a Python file. However, when I run the file, I get a ModuleNotFoundError.

Attempted steps and checks:

• I do not have multiple versions of Python installed.
• I activated the venv before installing the module and before running the file.
• VS Code says that it is using the Python executable in \venv\scripts.
• The module is in fact in venv\Lib\site-packages.
• I am running the latest version of pip both within and without the venv.
• I restarted VS Code.

Oddities:

• Running the file from the built-in terminal works rather than raising an error.
• which python in Bash returns /c/Users/Lyndon/Documents/VS Code/seatmap_parser/\Users\Lyndon\Documents\VS Code\seatmap_parser\venv/Scripts/python when it should presumably return C:\Users\Lyndon\Documents\VS Code\seatmap_parser\venv\Scripts\python.
• Adding the setting "python.pythonPath": "${workspaceRoot}/venv/Scripts/python" to workspace settings.json raises this error: The Python path in your debug configuration is invalid.
• If I deactivate the venv, install the module globally, and reactivate the venv, the file now works, leading me to think that perhaps somehow the wrong Python executable is running anyway.

I stand ready to check for any missed details upon request. Why isn't it working?
