I don't know why, but errors are starting to appear,
This error appears...

(Korean -> English Translated)

In Unity 2018 version, I used it according to the method in this repository. https://github.com/networm/NCrunchAdapterForUnity
Following this method, ncrunch worked normally with unity.
The ncrunch version at this time was 4.16.

But Unity was upgraded to version 2019 and does not work this way, so we are trying to figure out the cause.

I've done some deeper looking into Unity and how it works. It seems that Unity projects don't fit within the same general structure of VS solutions. The build system isn't the same and they use their own libraries as a foundation for the code. As you've identified, they also have their own customised version of NUnit.

To have them work under NCrunch, we would need to take a top-to-bottom approach that would require quite a bit of extensive integration, designing a lot of NCrunch around how they handle things. Probably not impossible, but also not something we would be able to handle in the pursuit of resolving a support issue. Basically, it's a whole different platform, and we don't support it right now.

There may be ways to make your tests run under NCrunch by setting up shared code between a normal NUnit test project and a unity test project, perhaps with cross compiling, shared projects, or a lot of MSBuild and compiler conditionals. Unfortunately, I can't be of more help here. If you'd like to see support extended to this platform, I recommend submitting a feature request with uservoice. If enough people are looking to use NCrunch on this platform we may be able to justify introducing support for it in future.
