Installing software update hangs for a long time, then silently fails

On my MacBook Pro running macOS Sonoma 14.3.1, I am running Docker Desktop version 4.26.0 (130397) and am attempting to update to version 4.27.2 (137060).

It says Docker Desktop is ready to install and says “Installing update”—which runs for a long time with no apparent progress, then eventually Docker Desktop exits.

When I restart it, I’m still on 4.26.0.

Can anyone suggest how I might resolve (or make progress towards resolution) of this problem?

Thank you!
