My account was HDW banned for no reason.

I finished a comp game without a red screen or any sort of instance that a 3rd party software was giving me an "advantage" that was against riot TOS and or was a cheat or anything, when I finished the comp game I was shown a message that I closed out off then my game closed, then my riot games client opened too my account being locked and "permanently suspended", and told I was using "third party tools to gain an unfair advantage", even though I had nothing open except Valorant discord and Nvidia control panel. I have never one cheated on this game, my account is a year 1 account and I have played this game since release. I also play for an Esports team for Valorant that I now cannot play due to a perm ban that is wrongly placed against my account? I had nothing open whatsoever to enhance my gameplay, I simply got home and duo que'd. This ban makes complete 0 sense to me and I have never been banned for 3rd party software's in my 5 years of playing this game. Help me?
