hi, i am trying to run the QCG example 2 (https://crest-lab.github.io/crest-docs/page/examples/qcg/example_2.html) but it returns with the error:

however, another QCG example (QCG 1, https://crest-lab.github.io/crest-docs/page/examples/qcg/example_1.html) seems to work. I doubt something is wrong with --ensemble, the "ensemble" directory is always empty. my version is CREST Version 3.0.2, and xtb 6.7.0. Thank you!
