Dear Chris,
before calling hp.x with compute_hp = .true., you have to run it with
sum_pertq = .true.. This step is exactly what allows the code to build the
chis from summing over the response at specific q-points.
Here is the excerpt from INPUT_HP:

QE Users & Devs,
I am attempting to use the linear-response calculation of U values (hp.x). This
operation can take a lot of time, so much that my job times out before it
finished. I’ve attempted to divide the job into q-points using the `start_q`
and `last_q` options.
However, when I do this,
