Custom sign command failed with exit code: {:?}

Error message

Custom sign command failed with exit code: {:?}

What it means

Raised in run_custom_sign_command (invoked from try_sign_windows) when a user-configured custom signing command — with `%1` placeholders already substituted with the binary path — completes but exits with a non-success status. This is an external tool failure: the user-supplied signing tool rejected the binary or its arguments, and the exit code identifies how it failed.
