Reproduction steps

                {
                    CredentialsProvider = (_url, _user, _cred) => this.Credentials,                    
                    Checkout = true,
                    RecurseSubmodules = true,
                };
                 
                this.gitRepositoryPath = Repository.Clone(this.SourceUrl, this.WorkdirPath, cloneOptions);
                
                using (var repo = new Repository(this.gitRepositoryPath))
                {
                    var path = Path.Combine(this.WorkdirPath, "..", this.Branch);

                    repo.Worktrees.Add(this.Branch, path, false);
                }

Worktrees.Add エントリポイントから開始し、Windows 上で issue に記載されている feature/branch-name ブランチを使って失敗を再現します。worktree ディレクトリの作成を追跡し、スラッシュを含むブランチの追加が報告された例外なしで完了することを確認します。
