Could you help me with this qustion! Thanks in advance!

I also encountered the same issue as you, and maybe you can try my solution:

Open the .gitmodules file and change all submodule URLs from the format git@github.com:User/Repo.git to https://github.com/User/Repo.git.

Alternatively, try manually cloning them to the correct location, for example:

git clone https://github.com/g-truc/glm.git /path/to/neuralsim/nr3d_lib/externals/glm.
