managed_python3 alias unable to create venv

[pboushy]

In my old work MacBook Pro 2018 with macOS 14.7.2 and MacAdmins Python 3.9, I can run managed_python3 -m venv venv to create a virtual environment.

In my personal MacBook Pro (16-inch, Nov 2023) running macOS 15.3.2 (or 15.2) with MacAdmins Python 3.12.1, when I run managed_python3 -m venv venv I get:

Error: Command '['$REDACTED/venv/bin/managed_python3', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

If I instead run /Library/ManagedFrameworks/Python/Python3.framework/Versions/Current/Resources/Python.app/Contents/MacOS/Python -m venv venv it works properly and creates the virtual environment.

Same issue exists with 3.11.7
