Monterey update kernel panic
It appears Monterey 12.0.1 has been installed but during startup recurring kernel panics prevent startup so it never starts up. Computer is for all intents and purposes, bricked.

After using Software Update in System Preferences to download Monterey and going through the install process the computer apparently installed the update but would not complete the restart. I did a hard restart twice attempting to tweak the restart but after several hours with no progress I decided to erase the drive with Disk Utility and install Monterey with an installer I'd previously download from the App Store. This installation and restart went smoothly and I restored my stuff from Time Machine during the set up process.

Try booting in Safe Mode:

You may have some security software or something else using a kernel extension or system extension that is causing the kernel panic. These extensions have unrestricted access to the kernel at runtime. If the software is not compatible with Monterey it will crash the operating system. The extensions load at boot. Safe Mode should load without the extensions and other things. It's a minimal boot mode.
You will need to either upgrade the software that is causing the crash or you will need to remove it. Another source of problems is malware which may use extensions, etc.
I had to upgrade some software using a beta version from a vendor in order to be compatible with Monterey. Upgrading the very first day can be risky unless you have a super plain vanilla installation without any software dependencies adding risks. In these scenarios you need to make sure all that software is compatible with Monterey.
This has also happened maybe to me and I learned also that one colleague of one relative. My laptop is dead and it doesn’t not switch on. My Mac book pro is only one year old. It is really so untimely this happens when you are so busy and I imagine Apple Store may not give me a replacement and may make me waste time with repair. I may be obliged to buy one new one for urgent work. Thank you Apple for not warning that this upgrade may be defective and make you miserable. In addition, I used the online chat service and felt like an idiot saying obvious solutions I tried as a long term Mac user. If this issue is known please train staff and say right away to book with Genius Bar than make you waste 25 minutes of your life with anguish. Be careful with this update it seems death of laptop happens.
I did try Recovery without success, got an error but can't remember what it was. I erased the drive, installed Monterey and reloaded all my stuff from Time Machine. Thanks for your suggestions, I'll remember them if there's a next time.
could you clarify, please, with regard to erasing the drive
Did you have to boot the computer in target mode?
Did it actually start up in recovery mode?
You initially mentioned the the computer would not start up at all ...
I'm actually facing a similar issue, where the kernel panic will happen a few times in a row before I can start using my Mac mini M1 again, I thought it was my Bluetooth keyboard/mouse that is causing the issue by looking at the Kernel Panic log.
panic(cpu 4 caller 0xfffffe0018217e00): IOBluetoothHIDDriver::setPowerState(0xfffffe150e8ec4b0 : 0xfffffe0019a57038, 1 -> 0) timed out after 10198 ms @IOServicePM.cpp:5524
Debugger message: panic
After some testing by turning off the Bluetooth, that wasn't the cause. Then I started digging a bit more into the log, and I found that it always kernel panic at the last run kernel extension "com.apple.filesystems.autofs"
last started kext at 7084541292: com.apple.filesystems.autofs 3.0 (addr 0xfffffe001798c7e0, size 5560)

...
So I went and turned off the FileVault and give it a try. And guess what, I can no longer reproduce the kernel panic again, but at the same time I'm losing FileVault.
Of course, I tried to reinstall the macOS Monterey via macOS Recovery, and turned on the FileVault, it was working fine for the first day, then it kernel panic again the next day morning.
This doesn't sound like the same problem. The original post was about kernel panic at every boot never fully loading the operating system. However, you should certainly report this problem to Apple and the proper way to get this bug reported to the developers is to use the Apple Feedback Assistant.
https://feedbackassistant.apple.com
You should submit as much detail as possible, including the logs and the kernel dumps and the steps you took to recreate the problem. It's a bug that needs fixing.
Thanks James. I have reported this via Feedback Assistant with the documentation that Apple gleans through Feedback Assistant. I've been reading about this problem all over the internet so it's obviously not isolated to me. Agreed, it needs fixing.
Had the same thing happen on a MacBook that is a year and a half old. It’s incredibly frustrating that this OS update has essentially bricked my laptop and now I’ve been told to pay out of pocket since it’s out of warranty.
You've been told by Apple to pay out of pocket? When it was their update that bricked your laptop? When this has been documented many times? I think if Apple told you to pay out of pocket you should make a big stink because you're not the only one with this problem.
Yep, they wanted me to pay to ship it out for a technician to take a look ($687). The guy at the Genius Bar claimed that this was the first time he'd seen anything like this happening but now that I see other people have had this issue I'm going to raise a fuss.
Try starting in Recovery and reinstall macOS

thanks for your. suggestions, I eventually just erased the drive and reloaded all my stuff from Time Machine. Everything's working as it should now. No idea what was gumming things up.
What I did was erase the drive with Disk Utility, install Monterey and reload all my stuff from Time Machine. Not ideal, but it works.
You are quite lucky because mine does not switch on with all resurrecting options of Macs read everywhere.
