会话进行中,所有 pwsh 工具调用连续失败。真实错误文本:
Error: sandbox mode "workspace-write" is requested but no sandbox backend is usable on this host; refusing to run the command unconfined. Install bubblewrap or run a Landlock-enforcing kernel (Linux), ensure sandbox-exec is usable (macOS), or ensure the ACL restricted-token runner can start (Windows) — otherwise switch the consumer to danger-full-access. Runner failure: windows-acl-run: --temp is not an existing directory: C:\Users\86150\AppData\Local\Temp\dsh-X5ECMI
