BUG: crash in `uv sync --no-build --no-install-project`

[neutrinoceros]

XY problem disclaimer: what I was really trying to accomplish here was installing dependencies only, ref #1516

I understand that uv sync --no-build is a bit self-contradictory because it requires building the project itself but forbids building anything, but I was still surprised that adding --no-install-project didn't help

reprod

❯ mkdir test_pkg && cd test_pkg
❯ uv init --lib

Is this intended, and is there a way around it ?
