Console scripts in virtual environment do not output to terminal in git bash

I have console scripts in my virtual environment in `\env\Scripts`, installed with packages (e.g. black, pytest, coverage). If I try to execute these in Git Bash, the output is not returned to the terminal.

If I use the command line tool for e.g. black with a virtual enviroment activated in Git Bash, I get a blank line returned, but no response:

```
$ black version.py

```

If I invoke black through python, I get the expected response:
```
$ python -m black version.py
All done! ✨ � ✨
1 file left unchanged.

```

If I invoke the command line tool using black from the system interpreter (i.e. not using the virtual environment), I get the expected response:
```
$ black version.py
All done! ✨ � ✨
1 file left unchanged.

```

If I pipe the output to a file, I get the output in the terminal, but nothing in the file:
```
$ black version.py > test.txt
All done! ✨ � ✨
1 file left unchanged.

```

If I invoke the command line tool with Microsoft cmd, I get the expected response:
```
λ black version.py
All done! ✨ � ✨
1 file left unchanged.

```

If I invoke the command line tool with a blank virtual environment, I get the expected response.
```
$ python -m venv env
$ . ./env/Scripts/activate
$ pip install black
$ black version.py
All done! ✨ � ✨
1 file left unchanged.

```

If I try to pip uninstall black, sys.stderr seems to be missing:
```
$ pip uninstall black
Found existing installation: black 22.1.0
Uninstalling black-22.1.0:
  Would remove:

```

The script is where I would expect it:
```
$ which black
/c/Users/XXX/env/Scripts/black

```

I get similar results with coverage and pytest. I re-installed Git for Windows. I am using Python 3.9.9. It feels like an environment variable or something related to the PATH that messes up stderr/stdout.

I understand this is a very specific situation, probably related to the repository that I am currently working on (which I installed in editable mode with `pip install -e .`).

Could somebody point me in the right direction to fix this?
