What is the official website for the xp pen driver download?

I went to a website that had the download, but today I was using it when all of the sudden my Opera GX started making hundreds and hundreds of tabs, slowing my computer down. I'm not sure if I used a scam website, so can someone send the official one so I don't have the same problem? (Also, as soon as I deleted the xp pen download, my computer was fine.)
