The exception is telling you that the copy of Pydantic you currently have in the virtual-env is 1.x, while the OpenDeRisk codebase has already migrated to Pydantic 2.0+.
Any import coming from derisk._private.pydantic will deliberately abort if it detects Pydantic < 2, hence the stack-trace you see.

uv pip install --upgrade "pydantic>=2.7,<3"

verify

python -c "import pydantic, sys; print(pydantic.VERSION)"
