Now PhoenixMiner 3.5c is working without that "ERROR: Debugger found" error. Thank you!
I will create a pull request for
https://github.com/rainbowminer/RainbowMiner, so that they integrate the new version as soon as possible.
Did you ever check it together with OhGodAnEthlargmentPill on GTX1080Ti? Does it crash or will it work?
