PowerShell

Error message

PowerShell: {}

What it means

A PowerShell invocation launched with -NoProfile -NonInteractive -ExecutionPolicy Bypass exited with a non-zero status; the {} is PowerShell's trimmed stderr. It is the single failure path for every shell script used by list, remove, and restore, so the failing script determines the real cause (bad cmdlet output, missing app entry, execution policy overrides).

Solutions

1. Inspect the PowerShell stderr in the message to see which part of the script failed
2. Run the same script manually in PowerShell to reproduce and diagnose
3. Ensure PowerShell is available and not blocked by group policy or antivirus
