Can you please try to synchronize the replica using Desktop 10.1/10.0 and check whether the issue is reproducible.
The Bug has been fixed at 10.3 as per the information provided in below link:
Based on this discussion and another one, I am currently attempting the same synchronize using Desktop 10.1 instead of 10.2. The synchronize is still running on 10.1 which is better than the crash we experienced on 10.2 within 30 seconds so I am hopeful!
If you were indeed hitting that Bug, them I'm pretty sure that the synchronize will complete successfully on Desktop 10.1
Post back here if you still observe any issues on 10.1.
Note: This Bug is supposedly fixed at 10.3.
