There's another similar report to this at in which synchronization of large playlists halts partway through the operation, though in this case it doesn't crash.

Debug log VH7MN16IZ2

This user also was syncing with MMW4.

EDIT: based on Martin's review of the logs, this is due to a timeout in MM4 for a particular file. So this particular issue is likely an MMW4 issue that might be fixed in MMW5.

Note: the original user indicates that it might be related to a problem deleting files. Does MMA Wi-Fi Sync verify permissions (and prompt the user if necessary for the needed rights) prior to each operation?

Log ID: WC42NXH5V8, Log ID2: FW1R9ST73P - The database was deleted during sync because it was corrupted. Probably because of a crash. Improved logs + a bunch of crash-log fixes.
Log ID3: VBEIBZUB2Z - playlist deletion fails, missing write permission. Added permission request before deletion.

Fixed in build

VH7MN16IZ2 & 85S5SXJ3NW - ConnectTimeoutException -> Asked user to try to turn off battery optimization.
I'm marking it as resolved until response and decreasing the priority.
