There's something wrong with the Radeon graphics drivers in your setup. My recommendation is to run DDU and start fresh with the latest Radeon drivers from AMD website. Disconnect the eGPU completely when you remove the drivers. Once the Mac mini restarts, hot-plug the Vega 64 eGPU then wait for Device Manager to detect. You can proceed to install Radeon drivers. When the installation completes and prompts you to restart, don't do it through the installer. Choose the Start button then Shutdown. You can then switch the HDMI cable from the back of the Mac mini to the Vega 64 eGPU. The Mac mini should be able to start using the eGPU in Windows if all goes well.
