Description
Plugin updates fail when multiple Copilot CLI sessions or VS Code windows are open, even when the plugin is not actively invoked or being used by those sessions. The update appears to be blocked by file locks held by unrelated processes or sessions.
Impact
Updating a plugin currently requires closing and reopening every Copilot CLI shell and VS Code window. This is disruptive and can prevent urgent plugin updates from being applied promptly.
Observed error
Installing plugin "Agentic-Workflows@CalOps-Hub"...
Failed to install plugin: Failed to install plugin: Access is denied. (os error 5)
Expected behavior
Plugin updates should succeed when the plugin is not actively in use. If a file lock makes an immediate update impossible, Copilot CLI should identify the process or session holding the lock and provide targeted remediation, or support a deferred or atomic update without requiring all Copilot CLI and VS Code sessions to be closed.
Actual behavior
The update fails with a generic Access is denied (os error 5) message while other Copilot CLI sessions or VS Code windows are open, without identifying the locking process or offering a recovery mechanism.
