UNO Board suddenly not working on either pc?

Hi guys and girls.

So my uno board I have been using without issues for some time, using a mixture of things such as running WS2812B's, and playing with a small OLED screen.

Today a 5M reel of WS2812B's arrived and naturally I couldn't wait to play with the FastLED library.

Suddenly my uno us not playing ball. When I plug it in, the either PC makes the sucsessful acknowledgment of a new device - both pc's allow me to "Get board info" which tells me the board is detected okay. Whenever I upload to the uno, it comes back with the infamous "Programmer not responding" when it was working just fine yesterday. My issue with whatever the actual issue is, is that every single time I try to upload it gives me a totally different "RESP=0X" code. I mean litterally every time its something different?!

I've reinstalled drivers, ive restarted both PC's, and ive tried the loopback test which gave me absolutely no results using Serial Port Monitor. So what exactly am I missing here? Edit* I have also used putty with again, no loopback results.

The only thing I have noticed is the UNO's led's dont flicker at all where they normally would. Just the "ON" and "L" remain on and static, nothing else. The reset button on the board also doesnt do anything at all.

Any ideas where to go with this, other than the bin?!

I have been researching all day and all I have discovered is that apparently it being a different error each time is likely a "default" error something to do with communication.

Here is my most recent error message when trying to upload:
