Exception Trace

Create a clean environment with Poetry, then run:

Additional context
Pinning to an older version doesn't solve the issue.

> python --version
Python 3.12.7
> poetry --version
Poetry (version 2.2.1)

pyproject.toml

[project]
name = "poetry"
version = "0.1.0"
description = ""
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.12"
checkov = "^3.2.300" 

[build-system]
requires = ["poetry-core>=2.0.0,<3.0.0"]
build-backend = "poetry.core.masonry.api"

Step by step to reproduce:

mkdir poetry-checkov
cd poetry-checkov
poetry init
poetry install checkov

I see a similar issue encountered in this project: beartype/beartype#569
Seems to be an issue with how poetry handles markers. Can you try this pyproject.toml:

[project]
name = "poetry-checkov"
version = "0.1.0"
description = ""
authors = [
    {name = "Your Name",email = "you@example.com"}
]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.12"

[build-system]
requires = ["poetry-core>=2.0.0,<3.0.0"]
build-backend = "poetry.core.masonry.api"

Then run poetry add checkov ?
This installs checkov 3.2.487 for me and I'm using poetry 2.1.3.
