Blackwidow Chroma V2 doesnt work anymore

At first it all worked fine but when i was starting a game the lighting suddenly went off. I didnt think much about it but soon realized my keyboard wasnt reacting anymore. I tried plugging it out and back in but it didnt work. All that came was "Razer Bootloader". In my device manager it was also only shown under unknown devices as "Razer Bootloader". Tried uninstalling every razer programme and reinstalling it but it didnt help. Also tried to use it on a diffrent pc and it also didnt work because there was apparently no driver installed even though there was. Does anyone know what i could do to fix this?
