im not sure, but maybe when you specify path, docker thinks theres two paths separated by :, also in linux to specify path you use forward slash /, so maybe puting in quote maarks would work, e.g. "D:\Pictures":/pictures/ and then looking for /pictures/ inside the container
You shohld also try checking logs when adding external library on immich with docker logs --follow immich_server
