Mac book air(2019) key board running Catalina 10.15.4 is unresponsive on login when connected to the internet via Wifi.

Keyboard accessible if internet connection is interrupted. Otherwise the keyboard becomes responsive after a long wait of 60-100 seconds.

Solutions like resetting SMC using control+option+shift +power key did not resolve the issue.

The finger print enabled power button remains responsive throughout.

Kindly advice on a possible resolution.

Thanks in advance
