IDE NOT WORKING- serial monitor

Development Tools IDE 2.x
1

My serial monitor is not working, I can send code to my UNO R4 WIFI and get a conformation that it works, the 4 motors have got on 2 h-bridges I have got running. However can not get a serial print response from the switches.

I have tried to change the com port and cable, re installing ide, restarting my windows laptop, taking the shield off the UNO, leaving over night all off, I have also run a PowerShell with this command: *& ".\Arduino IDE"* , which was recommended in a previous post. I can upload it if it is useful as I am not really sure what to look for.

Does anyone have any idea if it is a hardware or a software problem, or even better a fix.

Start by trying a simple sketch that prints "Hello World" to the Serial monitor at intervals in the loop() function. If it does not work then post it here

I have just tried to run that code and nothing is being picked up. Here is a screenshot for IDE

Shouldn't there be a Serial.begin() in there somewhere ?
