Hi, yes, the issue has been resolved and UE5 is no longer crashing.
However, I’m now experiencing a problem with FaceSync (Lip Sync). There is no audio playback, and the MetaHuman does not perform any facial movements or gestures, even though Lip Sync is enabled and the mode is set to MetaHuman.
The only response I see appears in the widget; there is no audio or facial animation.
I have followed this tutorial exactly ([https://www.youtube.com/watch?v=4fMCKkrfyaA](https://www.youtube.com/watch?v=4fMCKkrfyaA)), but I still cannot get the MetaHuman to gesticulate or produce any sound. The responses only appear in the widget and are not played as audio.
Could you please help me resolve this issue? Or is this something that is still being worked on?
Thank you very much in advance.

Please do not use GCP voices. Make sure you are using other voice providers.

Thank you very much for the update.
I wanted to ask if it will be possible in the future to use GCP voices. We’ve found that they provide the best quality when working in other languages such as Spanish, Catalan, or Galician. For us, Spanish is especially important, and at the moment GCP voices deliver the most natural and accurate results in this language.
It would be fantastic if you could consider integrating them at some point. Hopefully, it can happen soon.
Thank you again for all your responses and for your continued support.

Could you please try the GCP Chirp voices? The other (older) GCP voices are going to be deprecated.
You can recognize Chirp voices by their names, which include a description in parentheses, for example:
> Orus (Robust, Commanding English Male Voice)
Look for this kind of naming pattern and test those voices for your languages.

I have tested the recommended GCP voices, but many of them present issues during playback: the audio cuts out or becomes distorted in the middle of the response.
Do you think this problem will be addressed in the future? Good pronunciation in languages other than English is very important for us, so we hope this can be taken into consideration.
Thank you very much for all your responses.

I wasn’t able to reproduce this issue on my side with the GCP voices. Could you please share your Character ID and, if there is any error shown in the logs, the exact error message or a screenshot?
With those details we can investigate more precisely what is causing the audio to cut out or distort.
