Possible regression in 1.16.3: hatch shell fails with TypeError: Project.prepare_environment() missing 1 required keyword-only argument: 'keep_env'

[ltdroy]

After installing Hatch 1.16.3, the hatch shell command fails with a TypeError. This appears to be a regression as it works correctly in 1.16.2.

Environment:

Hatch Version: 1.16.3
OS: macOS (Apple Silicon)
Python Version: 3.13 (and also reproducible on 3.14)

Minimal Reproducible Example:

pipx install hatch==1.16.3 --force
mkdir hatch-bug-repro
cd hatch-bug-repro
touch pyproject.toml
code pyproject.toml

pyproject.toml added:

[project]
name = "repro"
version = "0.1.0"

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

hatch shell

Workaround

pipx install hatch==1.16.2 --force
hatch shell

I think this is a duplicate of #2164 and fixed by #2165. Just waiting for new release on pypi.

ps. thanks for including the workaround pipx command, that was helpful.

Ah you're right - closing as duplicate.
