"You have been detected running cheating software"????????????

I just installed PoE2 last night after not playing it for like 3-4 months, and the first thing I see is this upon logging it. It says "This is your first and only warning"

Like what bruther? I've never hacked in PoE, or any online game for that matter, in my life. So what is this exactly??

I've had cheat engine installed for over 6 months when I used it for Final Fantasy X and X-2 since Farplane Editor requires it, and thats it...It's also not running right now its just installed somewhere on my computer.

So I highly doubt that's it? Idk someone please enlighten me.

ReShade? Ultrawide "fix"?
