However, you often fail to get the update but encounter the error "A critical software update is required for your Mac, but an error was encountered while installing this update." It is often accompanied by a further note saying that "Your Mac can't be used until this update is installed." and the options to Shut Down and Try Again.

If a valid preflight doesn't exist, your Mac will require an internet connection, prompts the Setup Assistant, and asks you to install the critical software update, which is essentially the update for Touch Bar's embedded OS.
Based on the posts of affected users, the 'A critical software update is required for your Mac' error usually occurs after the Touch Bar stops working, wiping the whole startup disk, an unexpected shutdown, or a recent macOS reinstallation or upgrading (possibly failed), especially after updating to macOS Monterey.
If you can't pass the critical software update loop, but the Touch Bar still works fine, try pressing the power button to forcibly shut down your Mac and connect it with an Ethernet cable. After that, you can restart your Mac and select Ethernet in "Other Network Options" to continue the installation.
Suppose the Ethernet connection isn't helping or available; try connecting to another WiFi network or using your mobile hotspot to install the update. Chances are, the unstable internet connection is the only thing you need to deal with.
External peripherals, including USB hubs, monitors, hard drives, etc., also may prevent macOS from loading the separate OS (bridgeOS) for Touch Bar to start. So, suppose you are using multiple external devices when experiencing "A critical software update is required for your Mac." on Monterey. In that case, it's worth unplugging them (particularly the webcam cable), force shutting down your Mac, and trying again.
