Sorry to hear about this experience. Would you mind checking if all of your work on Fresco has been synced here: (https://assets.adobe.com/cloud-documents)? If yes, kindly try removing and reinstalling Fresco to check if it helps.
If the issue persists, please share a few more details, like the make and model of the device you are using, the exact version of the OS and Fresco installed, and a screenshot/screen recording of the problem so we can investigate this further.
