I'm sorry to hear about your experience. Would you mind checking if your work is still available online (https://adobe.ly/3O1mGhR) and reverting to an earlier version of the cloud document (https://adobe.ly/3O1mGyn) to see if it helps?
I'm sorry to hear about your experience and for the delayed response. I hope the problem is resolved by now. If not, kindly share more details, like the OS/Fresco version, whether Fresco behaves this way when working with a particular file/feature and a screen recording of the problem, so we can investigate further.
