Win 11. python 3.9 cantera 2.6.0a
After I installed the ctwrap I try to run the example cases by running the commend line:
ctwrap run freeflame freeflame.yaml --parallel --strategy sequence

Error returned:

same result returned using the jupyter notebook as shown below

ubuntu also gave the same error

Thanks for reporting ... I haven't worked on this project in a while; there have been some changes upstream in Cantera, which is the likely culprit here. Is there a reason that you're running an alpha version of Cantera, rather than 2.6?

Thank you for reply! I use alpha version only because I installed the Cantera from the dev source long ago and did not update it, is there a requirement for the stable version and will this project be updated in the future?
