Error importing hopsy

Hi, I tried to install and use hopsy yesterday but upon importing it my kernel would always die showing the following error message:

Excerpt 1:

Excerpt 2:

I have since re-installed miniconda several times and also tested it on my private PC at home with the same result every time. When I asked Max Siska to create a new environment and test it as well, the problem did not show up despite there being no significant differences between our installed packages/versions.

Regarding excerpt 1, the only solution I found through googling was to install zlib which is already installed in the python environments I used (I think it's co-installed with a package or possibly with hopsy).

Regarding excerpt 2, it seems like there is a conflict between two versions of the hdf5 package but even if I manually force the installation of version 1.12.1 (version 1.12.2 does not even exist) the same error shows up. In Max's environment the hdf5 package did not show up under pip list but even when I replicate his steps exactly the error persists.

The python versions tested were python 3.8.x and python 3.9.x and hopsy was installed via pip install hopsy in a fresh environment from a fresh installation of miniconda. Aside from hopsy, only the ipykernel package or the jupyter packeage was installed.
