Why is my computer creating a D drive when I run multiplayer pixel streaming? [closed]

I tried multiplayer pixel streaming with Unreal Engine but it failed. When I open a different port and connect to the local host, the following message appears. As a result of checking this problem, this message appears because textures cannot be imported Inframe from D3D11 and CUDA. The problem is, I don’t have a D drive.

Someone mentioned that Unreal Engine is not initialized, causing this problem. But I don’t know how to solve the problem.
