Fortnite PC, please help. It hasn't worked for 1.5 years?

I've been playing Fortnite on PC since Season 2. I was very good at the game and played Fortnite on PC almost every day. It was all good and I kept getting better at the game. It wasn't until season 6 or 7 (can't remember) that I played a normal round of solo and suddenly I was kicked out of the round. I thought it was a bug or something, then I got a message with somehow you were kicked because of proxy, hacking, VPN or the like. I was shocked. I started again and I was kicked again. From that point on I tried to find out what was going on and to find a solution until Season 9. Did not work. Many said I had to change SSD or buy a whole PC to play again. And again, I don't use hacks, I had a lot of rare skins and I invested a lot of money in this game.
Now the question is, what can I do now, please?!
I'm now playing season 11 through this season on PS4 and I find it boring. Everyone kills me and I'm just sad…
I don't want to spend any money to get an SSD card or a WHOLE PC. So please help me!

The message you received from the server is correct and unambiguous. You have been banned. Whether rightly or not it doesn't matter, but if I were you I would just write to support.

In any case, it's not your hardware
