Sorry for the late reply. Can you also send me your flopy version to reproduce the error? I will test it on colab.
I tested the modflow_flopy inversion example and successfully reproduced the results on Colab with python==3.7.15/flopy==3.3.5 on Ubuntu 18.03. Below is the colab link. The script will take ~15 mins since the colab basic account request only 1 physical core/notebook:

My suggestions are 1) recompile mf2005 on your machine (use mfpymake) and copy it to ./input_files/ folder and run the script again. 2) if it does not work, create a virtual env with python 3.7.15 (and recompile mf2005) and test the script.
Best, Harry
Amazing project! I just compiled mf2005 on debian 11 and can run it just fine but I can't run the inversion in this example, because Modflow doesn't create a head file (I am using Python 3.9.13). All the input files are properly generated, but I think that the simulation doesn't terminate. Have you noted this before? Bernard
