Cannot run "import miceforest as mf" line

Question

I am trying to impute the NaNs in an all-count-variables dataset using the miceforest package, but I cannot get the import miceforest as mf line to run.

The (huge) error I get after running the import line:

Unexpected exception formatting exception. Falling back to standard exception

miceforest runs on lightgbm, so the first thing I did was try to install it through conda install -c conda-forge lightgbm to no avail. It frozes after the following lines:

(my-env) C:\Users\name\miniconda3\envs>conda install -c conda-forge lightgbm

Is the never-ending installation of lightgbm the issue? Does it take hours to install and should I just let it run?
