Razer BlackWidow TE Chroma V2 TKL Green Switches.

Hi guys, I hope that you guys can help me with this. I bought the keyboard back in 2020 and it has been working fine since then, but yesterday when I was playing the game "League of Legends" to be exact. The keyboard started to disconnect and re-connect. There was also no light when it was connected to my Laptop. I tried the factory reset on Youtube but did not fix it. The matter got worse as it also spammed keys when I typed. Please help!!
