Hi,

Thanks for reporting this issue. Please try the following solution and let
me know if it works.
On the directory you are working on, if your Hess Output File is *.out
check you have a file *_job2_internal.hess
If you have that file, rename it to *_internal.hess and try Run
Optimization again.

Best Regards
