I've seen programs blow up because they think they need to "canonicalize" the path, when all they actually want is a full path (a rooted path rather than a relative path). Canonicalizing the path resolves all drive letters and symbolic links. The Rust function that canonicalizes a path can fail on some mounted filesystems if the drive letter wasn't registered using the Windows Mount Manager.
