For everyone here having issues (iPad Pro or otherwise):
This usually does the trick for me if Rush stalls out (I've identified one particular audio clip that causes issues in my projects, but it could vary from person to person and device to device):
- Close out your project, and sign out of Rush and Creative Cloud ON ALL DEVICES.
- RESTART YOUR DEVICE/COMPUTER, and make sure you don't have any memory-intensive ("RAM-hogging") apps running while you're starting up (I never run Photoshop, Illustrator, or Microsoft Office apps while working on videos).
- Sign back into your Creative Cloud Desktop App.
- For Windows Users: Hold CTRL + SHIFT buttons while starting Adobe Rush - this will tell Rush you want a "fresh start" without losing your projects; it will open the Starter Tutorial like you were starting for the first time - simply close the tutorial, and your projects will be available.
- Open your project, and BE SURE TO WAIT for it to FULLY SYNC. Then try editing and/or exporting, and you should be good to go... but just in case:
- IF NEEDED:
-double check that any Adobe Fonts you may be using are activated and connected
-re-add any missing assets to the project bin
- Last Resort: DUPLICATE the project and try working from the fresh copy.
Hope this helps!
