Not able to build and run with HDRP

    I'm running Unity 2020.1.3f1

    This happened with the HDRP option enabled on the project
    When I try to build and run, I get the error below. I also tried doing a build and run from a fresh start with nothing added or removed, same error received.
    If I run with the 3D option, I have no issues with build and run.

    I'm rather new to Unity so not sure why or how to fix this issue.

    Hellow. Welcome to this forum! I'm a user like you.
    So looking the first error looks like il2cpp is triggering the problem.

    HDRP is a more advanced topic: I suggest using the build-in default rendering instead of URP or HDRP.
    Anyway: Here is a tutorial on how to set it up:
    https://learn.unity.com/project/up-and-running-with-hdrp

    Returning to your problem,
    Do you have installed the package il2cpp?
    Is IL2CPP installed and set up correctly?

    https://docs.unity3d.com/Manual/IL2CPP.html

    As to how I understand, essentially C# is more simple to use but slower to run. IL2CPP converts the Unity C# to C++. So it runs faster becue uses the C++ compiler. "IL2CPP" is the conversion system. For example, if you divide 0/0 in c++ you get an error. Not controlling that the game runs faster. But sometimes is not what you what and it has some checkbox that need to be configured:

    https://docs.unity3d.com/Manual/IL2CPP-CompilerOptions.html

    The "emit null checks" in the message warning error: can be that need some of these booleans to be setup?

    Hi AlanMattano
    Everything is installed from the Hub with as far I know no issues.
    il2cpp is also installed as a module from there (it would say il2cpp not installed if I tried to build without it).
    I wasn't aware that it was possible to click the error and see full details on the error and here I could see that to build it wanted to have visual studio 2015 and 2017 installed... after those installed, build and run worked perfectly.
    Thanks for taking the time in helping!
