Unable to generate Video in Video Studio with cloned voice

When trying to generate video in video studio with cloned voice then I am unable to do the below items:

On clicking the Generate Video button, The final "let's go" button doesn't load and it just keeps buffering for Video Length, Credits.
In the voices section, Unable to play the sample of cloned voice.
In Video studios script section, On clicking the listen button it keeps buffering instead of actually speaking the script.

I have a Launch Subscription and cloned my voice successfully , It appears in voices section. But still I am unable to create Video as it gets stuck in buffering, While this doesn't happen when using the pre-defined voices.
