Text to avatar (beta) generate video failure

Text to avatar (beta) generate video - I have tried to generate  a text to avatar multiple times over the last couple of months. It gives a progress bar and at the end of the progress, it says "something went wrong".  It once took credits for that, for which I was credited. I am getting woried I will again loose credits if I attempt another generation. My current credits expire in two days. Am I doing something wrong? This generation is important to my workflow, and has worked well in the past. Please help.
