The icon on the pgAdmin4 window has gone missing. Is there a way I can restore it?
I've checked pgAdmin 4\v7\runtime\package.json which lists "icons": { "256": "assets/pgAdmin4.png" }, but I'm not sure Windows' icon is derived from that. And I can't seem to find any *.ico in the pgAdmin 4 folder...

This is likely related to the known issue with NW.js. Until it's fixed, pgAdmin can move back to 0.72.0.
