I've decided to completely reimage the SD card and hope for the best. I can't get ZeroTier to work either. There's something very, very weird going on with this installation. I'm really sorry for wasting your time as for whatever reason(??) it looks like it's this install that must surely be at fault. Somehow. Thank you.
Well hopefully some of the changes we made will benefit others also - so not a problem.
Let us know how you get on.

Hi ! I've just read all of @dceejay and @dclear msg here, trying to find out a similar problem here. Running on raspberry pi 4b, I updated nodejs, npm to latest version and them when I reinstalled node-red, it can't start on boot anymore. I did all this updates because I couldn't use the node "tf coco ssd", I only have successful deploy with "cocossd" Uninstalled and installed so many times today :(.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials

pi@raspberrypi:~$ which node-red
/usr/local/bin/node-red
The msg EADDRINUSE: address already in use 0.0.0.0:1880 means you already have a node-red running.
What happens if you open browser and point at the IP of the Pi and enter ip_address_of_the_pi:1880

Thanks! I've just close the browser and this EADRRINUSE didnt shows on node-red start. Could you imagine what's going on with my systemctl ?
Closing the browser will not have changed that. Something else must have done it.
I think that you did not use the recommended script for installing node-red.

Thanks for helping me. This is the last startup I've made, Today i'm going to try reinstall again.

Hi there Ć°. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.

I think followed wrong tutorial to get the latest node.js. But now hopefully @Colin just have help me. Its solved. Thank you all
Running Node-RED install for user pi at /home/pi on raspbian
This can take 20-30 minutes on the slower Pi versions - please wait.
Stop Node-RED \u2714
Remove old version of Node-RED \u2714
Node option not specified : --node12, --node14, or --node16
Leave existing Node.js : v16.13.0 Npm 8.1.0
Clean npm cache -
Install Node-RED core \u2714 2.1.3
Move global nodes to local -
Leave existing nodes -
Install extra Pi nodes \u2714
Add shortcut commands \u2714
Update systemd script \u2714
Any errors will be logged to /var/log/nodered-install.log
All done.
You can now start Node-RED with the command node-red-start
or using the icon under Menu / Programming / Node-RED
Then point your browser to localhost:1880 or http://{your_pi_ip-address}:1880
Started : dom nov 21 11:58:29 -03 2021
Finished: dom nov 21 11:59:57 -03 2021
pi@raspberrypi:~$ sudo node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.16.115:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org
Starting as root systemd service.
