Failing tests on Windows with GH artifact wheels

Using an appropriate wheel from https://github.com/CadQuery/ocp-build-system/actions/runs/8367440736

I created a conda environment and discovered that 2 tests from CadQuery/cadquery are failing. Here is my setup process:
```sh
conda create -n env1 python=3.11
conda activate env1
pip install cadquery_ocp-7.7.2-cp311-cp311-win_amd64.whl # this also installs vtk=9.3.0 on my system
pip install cadquery
pip install ipython pytest
git clone https://github.com/CadQuery/cadquery.git
cd cadquery
python -m pytest
```
fails 2 tests and returns:
```py
