Hi there,
Sorry to hear about the trouble. Please try the steps shared below:
- Sign out of XD and Adobe CC Desktop app.
- Close CoreSync and all Adobe related processes from Task Manager/Activity Monitor.
- Sign in on Adobe CC desktop app and launch XD from there and check if it works.
If this doesn't help, please share a few more details like:
- A screenshot of the About XD info page and the Operating System.
- Is it happening with a specific file or multiple files?
Regards
Rishabh
