Strange thing is that I have also installed singularity and I even checked if it was compatible on CKAN. I'll list the dependances I downloaded and maybe see what I forgot.
Singularity, kobernicus and ksp community fixes.
I don't know what's going on. Even with dependences, both the worm hole and the black hole doesn't exist. Btw in case if you need to know, I am on windows 11.
