Research direction
Start by reproducing the failure in Canvas using the chromium-control-canvas extension on the listed Copilot App and macOS versions. Investigate why the extension fails to start rather than retrying it; done means it starts successfully and remains available across projects or workspaces.

Description
Bug Description
The Canvas page reports:
Some canvas extensions couldn't load.
The chromium-control-canvas:chromium-control-canvas extension repeatedly fails to start and shows:
Failed to start or stopped unexpectedly.
The issue occurs across multiple projects/workspaces, so it does not appear to be specific to a particular project.
Clicking Retry does not resolve the issue.
Expected Behavior
The chromium-control-canvas extension should start successfully and be available in Canvas.
Actual Behavior
The extension fails to start and is listed under "Some canvas extensions couldn't load."
Environment
