Coder Connect fails on workspace start; wgengine watchdog triggers

Returned to my Windows desktop and checked Coder Desktop tray app; Coder Connect was running, showing me all my stopped workspaces.

I started a workspace from the web and waited for it to come up.

It shows Coder Connect running, but no workspaces.

In the log, it shows a wgengine watchdog failed:

Inizia con il log completo allegato e le voci di Coder.Desktop.Vpn.Service.TunnelSupervisor relative al timeout del watchdog di wgengine durante l'avvio del workspace. Riproduci il problema su Windows e traccia le operazioni Reconfig e Ping; il lavoro è completato quando Coder Connect elenca il workspace avviato senza il timeout del watchdog.
