High Ping Only On League Of Legends

[Jack678]

Hi guys, just need some help with this as LoL's support is just garbage. My ping would randomly shoot up after around 6PM, from 50-60(Normal) to 100-150 until about 12AM. When my ping is at around 100-150 i would go onto test my ping etc. and it would be like 30 - 40. I have tried everything, disabling Ipv6, turning off windows firewall and windows defender. But when i run a clean boot of windows i cant check my ping to the lol servers through run + cmd. If anyone has any advice or help it would be very much appreciated, thank you.
