My STM32 WBA55CG was working absolutely fine yesterday and today it seems that, my system refuses to find it. I have checked that i can see it from my device manager but when trying to flash it. It doesn't seem to do anything.

When i remove the JP2 jumper, it seems to turn on LD4. I have not removed the jumpers at all. They are as they came to me in the box. 

 

I am able to see it on the STLink Upgrade utility which is in the cube ide. 
Could it be because the ST-link chip is working fine but something is wrong with the microprocessor?

Hello @BadEngineer and welcome to the ST Community 😊.

If you remove the JP2, you will not be able to program or debug any code. If not, can you please try to upgrade the St-link firmware using CubeMX. Can you also ensure that you are using a data cable and not just a charging one. 

Also, please ensure that the Jumpers are set as mentioned on the STM32WBA Nucleo-64 board (MB1863) - User manual

Best regards.
