PowerShell 错误:

Error message

PowerShell 错误: 

What it means

LoadAppListAsync enumerates installed AppX packages by running a Get-AppxPackage PowerShell script. If powershell.exe exits non-zero, it throws "PowerShell 错误: " + stderr. In this app the exception is caught locally and shown as a "加载失败: ..." list item rather than crashing.

Solutions

1. Check the stderr text after 'PowerShell 错误: ' — it names the real cmdlet/policy failure.
2. Verify the service: `sc query AppXSvc` and start it if stopped.
3. Test manually: run `powershell -Command "Get-AppxPackage"` in a console; if it errors on execution policy, adjust or use `-ExecutionPolicy Bypass` in Arguments.
4. On stripped/Server SKUs where Get-AppxPackage does not exist, treat the empty list as normal instead of an error.
5. Repair the component store / user profile if the cmdlet reports deployment errors (DISM /Online /Cleanup-Image /RestoreHealth).

Example fix

// before
p.StartInfo.Arguments = $"-Command \"{psScript}\"";
// after
p.StartInfo.Arguments = $"-NonInteractive -ExecutionPolicy Bypass -Command \"{psScript}\"";

using var probe = Process.Start(new ProcessStartInfo("powershell.exe", "-NonInteractive -Command Get-Command Get-AppxPackage") { UseShellExecute = false, RedirectStandardOutput = true, CreateNoWindow = true });
string probeOut = probe.StandardOutput.ReadToEnd();
probe.WaitForExit();
bool appxAvailable = probe.ExitCode == 0 && probeOut.Contains("Get-AppxPackage");
if (!appxAvailable) { /* show UWP list as unavailable instead of erroring */ }

try { await LoadAppListAsync(); }
catch (Exception ex) when (ex.Message.StartsWith("PowerShell 错误"))
{ MessageBox.Show($"无法枚举 UWP 应用：{ex.Message}\n可能被策略限制或 AppX 服务被禁用。", "提示", MessageBoxButtons.OK, MessageBoxIcon.Warning); }

When it happens

Trigger: Calling LoadAppListAsync (on Appx control load or refresh button) when powershell.exe returns non-zero: PowerShell blocked by execution policy/AppLocker, Get-AppxPackage cmdlet missing (very old Windows / stripped-down LTSB builds), AppX deployment service (AppXSvc) disabled, or profile/registry corruption making the cmdlet throw.

Common situations: Heavily debloated Windows images with AppX services removed; corporate AppLocker/WDAC policies blocking unsigned PowerShell; broken user profile where Get-AppxPackage throws permission errors; running on Windows Server without the AppX module.
