The Loopback test usually doesn't work...
It is due to 1k resistors and signaling LEDs, right? Shorting pins 2&3 then should work. (+1)

That's the way I understand it.

Thanks for the +1. :)

Hi,

Thanks for your assistance!! I think I have managed to get it working again by timing the release of the reset button with when I hit compile. I can now upload a sketch again BUT only some 2/3 then I am back to the same issue again.
My next question is must you remove the USB and circuit before you upload again? or should you just be able to upload one after the other without disconnecting?

The reset pulse do not pass that you have to use the button. Check this, use LED with resistor in series between VCC and RESET or with DMM.
Only ~2/3 of image. I have similar on Linux and MS Visual Code Studio. Make sure that another application doesn't operate with the port. It requires some investigation on the OS. Try unplug and plug after unsuccessful upload, but it is just shot into the dark. There is also probability of bad USB/serial transceiver. Should by good to test it with external USB/serial if you have some.
