Pixma G7020 Failed to open a connection with the device-21345 scanner with BigSur OS 11.5.2

I tried to connect to the G7020 wifi scanner with Canon IJ scan utility lite, but no response, and a message came.

Failed to open a connection with the device-21345

I checked many solutions with no benefit.

The printer is working wirelessly well and it's working with Windows 10, android and IOS

What to do to solve this problem?

Regards
