I was on with Apple support yesterday. They are allegedly aware and working on it.
They were not able to help me fix it so far but gave me some reset suggestions I will include below.
I WAS able to move my note from ‘on my phone’ to ‘iCloud’ and access it on a web browser following the link they sent. PHEW! (Sorry if this is not working for others).
Force restart instructions:
To start, may I confirm also if have you tried to perform a force restart on your device? Just to differentiate, restart needs to slide the power button to turn off the device while force restart requires pressing the correct buttons until it automatically restarts with Apple Logo.
Here’s how to do force restart: Shut down device then press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then press and hold the Side button until you see the Apple logo.
Online iCloud access:
May I confirm if you've already tried to check that particular note also on http://icloud.com after you logged in?

Your business and satisfaction are important to us, and we appreciate your understanding in this matter.
So while it is still one of the issues that is actively working on with by our engineers here on Apple, I kindly request for you to have a copy of that note from your http://iCloud.com and paste and create a new note on your app for your access to that note and to make sure you can still be use it.
That is the workaround we have for now for you to continuously use the that particular note.
