Hello again and thank you for this report :-) This looks like an annoying multiprocessing error that may occur on Windows (it's it's probably an optlang problem with specific solvers :3). Hence, it would help us to know if this error is resolved by setting the number of processes for multiprocessing to 1 in the cobrapy configuration (unter 'Config'->'Configure COBRApy')?
