I reproduced the error on my end with Python 3.10. The GitHub version is updated to fix the error as Sharbano suggested and tested. To update your version please run those commands irrespective of the WIEN2k version:
cd $WIENROOT/SRC_BerryPI/BerryPI git pull This will update BerryPI to the most current version (including updates to the Chern number and hybrid Wannier charge center calculations for topological materials). Thank you again, Sharbano!
