Anything else relevant?
It started to break in 1.27.0, and 1.27.1 doesn't solve it.
Running Gazelle from outside the venv works as expected.
I have also tried creating the virtual environment with python -m venv .venv to rule out any possible issues
with our rules_pyvenv, but it also fails with the same error.
