Error with ICBM 2023 using DuNeuro

Bugs
1

Hi there!
I have been using DuNeuro Fem for computing head models for a while, It usually does it very fast,
I updated Brainstorm recently and now It stucks on DuNeuro computing,

Message: Computing Leadfield....

and that's it, it simply does not finish and gives no more messages

I have not changed any parameters, I'm doing the way I always do
I'm using default anatomy (ICBM 2023) and I created the Fem mesh,

Help please!

UPDATE: I used ICBM 2022 instead the newest version and it worked!, head model was computed quickly and without any error,
Why???

As stated in the main paper, I believe this error is related to the head model construction or phase 1: https://www.sciencedirect.com/science/article/pii/S1053811922009727.

Can you check what is the difference between the mesh of these two version of the ICBM?
Have you used the same parameters?
There is probably an issue either at the segmentation step or the mesh generation step

Well, I tried again using ICBM 2023b for default anatomy, and Iso2Mesh-2021 and MergeMesh for generating Fem Mesh, I choose default options, but this time I got an error message about the tags of Tissues are nor recognized (????):

So I used iso2Mesh instead and I got no more problems, but it is weird
please help!
