Since today Indesign closes every few minutes itself on its own and disconnects from my account, so I have to restart it an log in again. Has anybody an idea what to do to solve this problem?
Which version of InDesign and OS?
How much RAM?
Try resetting your InDesign preferences to see if that helps:
1) Close InDesign
2) Double click on Adobe InDesign's icon to launch it
3) QUICKLY hold down Ctrl+Alt+Shift. (for Windows) or CTL+OPT+CMD+Shift (for Mac OS X)
4) When a dialog appears, ask you “Delete InDesign Preference Files?” Click Yes.
(If you don't see the question do it again.)
Indesign 16.0 X64, Windows 10 V2004, 32 GB RAM.
Tried what you said, after that indesign didn't start anymore at all. Restarted the system after that, then I could start Indesign again and now I am waiting if the issue persists.
I suggest you unistall InDesign, using the drop-down menu in the Creative Cloud app, and reinstall it again. If that doesnt solve the problem then unistall it once again and then run Adobe Cleaner before reinstalling InDesign again.
Sorry to hear about your experience. In addition to helpful response given by Derek, please follow troubleshooting steps given on this community post(https://community.adobe.com/t5/indesign/resolve-slow-performance-and-unexpected-behavior-of-indesign...). Hope it helps.
