The draw2agent canvas tool encountered an error while trying to capture the user's screen.

Error context:
{{ERROR_MESSAGE}}

1. Review the error message.
2. If the error implies the local server isn't running or there is a connection issue, please notify the user and ask them to fix it.
3. If it looks like a transient issue, you may try calling `launch_canvas` again.
4. Do not enter an infinite loop of retries. If it fails twice, stop and wait for the user.
