    After updating to 2023.3.25f1 from 2023.1.3f1 keep getting Internal build system error. BuildProgram exited with code -2147024809.
    Project if copied to other location without version control enabled (perforce) builds successfuly for android.

    Anyone getting this one?
    Or is there anywhere a list with internal build errors?

    I'm having this problem all of a sudden on 2022.2.19f builds for WebGL and it doesn't tell me what the problem is at all.
    For some reason it works when creating a build through Unity Cloud builds or Windows builds but then I can't reproduce a bug I'm having only with WebGL.

    Hey there, as it has been already stated, this thread contains a lot of different problems and possible solutions for them.
    If you get:
    Internal build system error. Backend exited with code 2.
    and you have MacOS 12.3 or higher and probably got this issue after upgrading your OS recently, you need to install python to solve your issue!

    Reason for this is that since MacOS 12.3 python was removed. The fastest way to install python on MacOS is

    1) Open your terminal and type
    2) xcode-select --install
    3) restart Unity

    here is a more detailed answer: https://apple.stackexchange.com/que...e-developer-path-when-attempting-to-use-git-a

    Cheers!

    Vraiment j'ai constaté ce problème est dû à la mis à jour de sécurité Windows! J’ai activé mon Windows aujourd’hui avec AACT Just avant de rencontrer le problème. Merci !

    Yeah, not for me. I was already on macos 13 and it worked, and then I upgraded unity and it stopped working.
    Also I already had xcode tools installed, so that is not the case.
    Not that it matters much anymore... I gave up unity on mac....

    Hello!
    I had this same issue on Mac using OS 13.4.1, Unity 2021.3.26f1 and Xcode 14.3.1. My project was building fine but then I changed the project's name. Something else may be responsible, but that was the only real change. After that all builds would fail quite quickly.

    I tried the erase the complete "<project name>/Library" folder as suggested here and it fixed the problem.

    Cheers!

    Deleting Library folder worked for me. I started having the issue right after importing the iOS 14 Ad Support package

    unity 2021.3.26f1 same issue when importing firebase analytics sdk 11.3.0
    i use mac and as soon as i import and press play btn it prompts me that firebase cppapp-11.3.0 not found
    and in the overlay mac security says that this aplication is from undefined developer and blocked it
    i allowed it from mac system prefrences and relaod unity to play the same error occues
    and when tring to build. the build fail with this error

    Edited:- Turns out my mac os is too old and there was no xcode installed
    so i had to download 10GB xcode 12.3 and install it
    what it did was allowed me to install python properly, its worth noting without xcode any installation of python was getting neglected.
    this resolved my problem

    I am still having this isuue on Unity 2021.3.9f1.
    1. The project never has this issue on Windows Unity, but only on some Mac Unity
    2. If I change ANY code of C#, I will have "Internal build system error. Backend exited with code 2", and then I cannot do anything. If I close Unity and reopen, the error is gone.
    3. I got this issue after I upgraded firebase recently. If I deleted firebase completely, this issue is gone.
    4. My mac version is 10.14.6, so I don't think it is python related.
    5. We are using Cache Server, which is set up on a Windows Computer.
    Editor log is something like this (when I am just adding space in AppSettingAssetEditor.cs);

    For me there was a issue in SDK networks at editor level which was causing this issue. My firebase was not getting connected with Python. I just update all the SDKs to latest and resolve all the issues not this error is gone.

    same isssue for us. we use Unity 2023.2.2. Crahs happens during build for WebGL, when Multithreading is activated. I think it's related to specific combination of Unity packages and Project settings, because project is empty.

    Here is log:
    Code (JavaScript):
    1. Build completed with a result of 'Failed' in 24 seconds (24224 ms)
    2. Internal build system error. BuildProgram exited with code 1.

    I have this problem after uninstalling VS2019 after getting a message I should build with 2022, I guess my project was building with 2019 despite that not being the reccomended version?

    Now i'm trying to fix it :/

    Deleting library folder and reinstalling unity has not worked.

    Unable to build IL2CPP in 2021.2 - Unity Forum

    This thread helped, it turned out I needed to install C++ tools in Visual Studio 2022, to do this go to the visual studio installer and select modify then add the C++ desktop tools (or maybe the game one too? I did both to be sure)
