Could you please clarify your exact version, do you use uv or not?

You may try this script which dumps the Python traceback after 10 seconds:

import venv
import sys
import faulthandler
faulthandler.dump_traceback_later(10, exit=True)
sys.argv[:] = [__file__, "digiven"]
venv.main()

Pip should not normally be reading from stdin. If you interrupt the process, you should be able to see from the traceback what was doing the read. Please try that and post the result.
