SimNIBS GUI loading data error

[gbaghdadi]

Hi,
I worked with SimNIBS and SimNIBS example without any issues, but today when I want to use it, I receive the following error after determining the m2m folder. Does anyone know the reason?
"simnibs GUI error operand could not be broadcast together with shape (3,)(0,)"

Is it possible that you are using a newer numpy version?
conda list will show which package versions you are using.

Just change the numpy version to a lower version.

Thanks all for your answer. I changed the numpy version from 1.25.2 to a lower version 1.21. but again I receive the same error. Do I need to install a specific version of numpy?
