Adobe is investigating this issue.

  1. Go to the macOS Finder menu.

  2. Hold down the Option key and select Go > Library.

  3. Navigate to: /Library/Preferences/Adobe/amecommand

  4. If this folder is present, open every subfolder in that location and check for a file called Trace Database.txt. If this file is present and it is empty, delete it. 


    Even if you find Trace Database.txt in one subfolder, continue to check all the subfolders for it. Ensure that you delete all instances of Trace Database.txt that are found to be empty.

  5. Now navigate to: /Library/Preferences/Adobe/dynamiclinkmediaserver

    Repeat instructions in Step 4 above.

  6. Close all Adobe applications.

  7. Restart Photoshop.


If the video rendering issue occurs again, repeat the workaround steps.
