Describe your issue

With condarc provided below, installing packages from a label channel fails, while conda works fine.

❯ micromamba install -c "nvidia/label/cuda-11.8.0" cuda-nvcc

critical libmamba Multiple errors occured:

Obviously, the returned URL includes label/label but it should occur only once.
