DX11 Renderer for Harry Potter 1 giving "Assertion failed" Critical Error when launching game

I tried to use this mod here:

 

I'm on a fresh install of Windows 11, and I'm trying to get Harry Potter 1 to work with this renderer. The game was already working, but looked pretty bad, before I tried to get this renderer to work.

I followed the instructions from the readme carefully, but when I launch the game I get this error:

 

What does this mean?? I can't find anything online with this exact problem. There were people that reported similar errors for Unreal, but so far I didn't find anyone reporting a clear solution. It seems like it has to do with MS Visual Studio somehow? Also, the details of this error message make no sense. The path of C:\HPBuild\... doesn't even exist. There's no HPBuild folder in C:\, or anywhere else, I think. 

I would really, really love some help. This is very frustrating and exhausting. 

 

PS: In case anyone else out there is Googling/searching this error, here's the error text, for the search engine:

Assertion failed: RenDev

[File:C:\HPBuild\WinDrv\Src\WinViewport.cpp] [Line: 342]

History: UWindowsViewport::OpenWindow <- UGameEngine::Init <- InitEngine

You consider that pirated? I was under the impression that it's abandonware, so that no one owns these games anymore.

Unfortunately abandonware is not legal term is still considered piracy despite how silly it is considering the game is unobtainable.
