Pixma G7020 scan communication error while using IJ Scan Utility


I have a Pixma G7020 printer/scanner.  I downloaded the MP drivers from the Canon website. My computer and printer are connected to the same wi-fi router.  The printer prints fine from my computer running Windows 11. Use the IJ Scan Utility app to try to scan.  When I select the auto button in the scan app the printer scanner starts scanning. However after the scanning stops I receive an error message--"cannot communicate with scanner."  Listed error codes are "2, 157, 50." 

I uninstalled and then reinstalled the MP drivers/IJ Scan Utility from Canon; I checked my Bitdefender antivirus and confirmed that IJ Scan Utility had permission to communicate with the computer; the computer is obviously communicating with the scanner because the scanner runs after starting it in the app; and I confirmed that the correct printer/scanner, "Canon G7000 series Network", is the selected scanner. Ultimately I don't get a scan of my document to save to my computer.  After wrestling with this for over 5 hours I am at a loss as to why the scanner is not operating correctly.
