Whatever update that was made just makes XD crash, constantly asking for login and when you close Coral Sync and Creative cloud and restart hence sign in again. Same problem occurs. Please bring back old update. Whatever you did isnt user friendly at all hence so frustrating. Actually I have failed to work the whole day because of the bug. Wish updating was optional
Sorry to hear about the trouble, we'll try our best to help you with it. 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 back in on Adobe CC Desktop app and launch Adobe XD from there and check again if it works or not.
