python3 inside venv gives termios.error: (25, 'Inappropriate ioctl for device')

I've been running a python script inside a virtual environment that I create with pipenv shell, it worked well.

I've always run the process from a bash script that changes directory to the folder containing the python script, activates the virtualenv with pipenv shell, then runs the python script, then exits the virtualenv.

However, I must have typed something wrong in the terminal and broke something, now I get this when I run the script inside the virtual environment:

Launching subshell in virtual environment...

termios.error: (25, 'Inappropriate ioctl for device')

I have uninstalled and re-installed pipenv but to no avail.

If I run the script without activating the virtual environment, I don't get the error above, but I have other issues.

What is causing this error? How can I get rid of it? Thanks.
