Error in pickling and loading mkm setup file in Python 3.10.13

[Shahriar58Hossain]

I am trying to follow the 'Refining a Microkinetic Model' tutorial for CatMAP, but am getting the following error when I try to run the model -

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

    448 except:

TypeError: a bytes-like object is required, not 'str'

During handling of the above exception, another exception occurred:

I'm also attaching the list of packages in conda environment.

What is the potential issue here?
