I reviewed your post and I understand that you are facing issues scanning after updating the operating system to Mac OS 11.
Don’t worry, I assure you I will try my best to get this sorted.
I recommend you uninstall the printer driver from the computer and then download and install it from the below link.

Also, uninstall and reinstall the HP Easy scan on the computer.
Let me know how it goes and you have a great day!
