A no-response symptom is not a source verdict
When the character appears but does not answer, the file may still be the correct file. The problem can be in the AI provider, a local model, a Bedrock world option, a disabled behavior pack, a wake phrase, or voice output. Replacing the download before testing those layers can turn one setup problem into several source problems.
Start with the smallest possible test. Load the exact project in a clean profile or clean world. Send one short typed message. Wait for a complete response. If text works, the base route is alive and the next layer is voice, audio output, microphone permission, or language support. If text does not work, fix provider, pack, command, or route identity before opening a mirror.
