Looks that somehow the current directory doesn't exit anymore OR it's non empty but only contains spaces or something like that. Besides the snippet below, RedirectingFileSystem::lookupPath(llvm::Twine const&) also calls `makeAbsolute` before `remove_dots`. Can you try to print `FileSystemOpts.WorkingDir`?
