my razer huntsman v2 tkl is in "razer bootloader" or in "device failed enumeration" state everytime

ive been using this kb for around month (i bought it from my friend), and for this month, i been constantly having "device failed enumeration", "device descriptor failed request" and razer bootloader. but sometimes i can use my kb perfectly without any problem. i deleted synapse 4 from my autostart, and kb It began to work better, but it still gives errors by the type of first and razer bootloader. what can i do??
