I created a third-person template project in Unreal Engine 5.5 and enabled Pixel Streaming, Pixel Streaming Player and Convai Plugin. Added my character ID and API key. Then, when I’m packaging I’m getting this error. Can you help me?

I have attached the unreal output log here.

Hello @Ravindu_Cooray,

**Welcome to the Convai Developer Forum!**

Currently, our Unreal Engine SDK does not support Pixel Streaming in Unreal Engine 5.5. If you wish to use Pixel Streaming, we recommend switching to Unreal Engine 5.4, which supports this feature fully.

Not OP but as I have a fully set up and running pixel streaming project in 5.5, downgrading back to 5.4 would be a bit of a hassle.  
Do you maybe have any updates on this topic or aproximations on when the fix for this will be available?

I don’t have an exact ETA at the moment, but we’re actively working on it.
