Hi, we need more information such as the version of Aodbe XD you are using, the version of the Creative Cloud App and what are the features of your computer.
Have you tried logging out of Creative Cloud and logging back in again?
The issue can also get caused by an outdated video card driver.
When did this start happening? Any particular event that broke it?
We would like to follow up on the issue you reported. Are you able to resolve the issue? Are your files opening up fine? Please feel free to update the discussion if you need further assistance from us.
We would be happy to help.
