Shuts down on startup

[SpruceFan]

...back from delivering the dog to the kennel.....

I manually reinstalled without doing anything, i.e. did as you asked. The same thing happened. The DSM version is DSM 7.1-42661 Update 1

When I check for a DSM update, Synology informs me that this is the most recent.

I'm very grateful for whatever help you can give me. Incidentally, I've been ruling Mo0deAudio on a Raspberry pi as renderer, it works much, much better than VolumIO although it is a nuisance to set up. Linn on an iPhone is my usual control point.
