    Could someone help me on this problem? When I try to build my Unity project for Mac, it works fine. But if I build for Windows, it gives me "Failed to load Mono". I restored the DLL files and everything

    You probably didn't copy all the files to your Windows machine. Try building to an empty folder and see if you missed any files.

    I can't do that now because of the time here. I will try that tomorrow and see if that works.

    Thanks @Tautvydas-Zilys

    I'd build to an empty folder and compare whether all the files are there in the build that doesn't work.

    I suspect you didn't include all the files from the build into your installer. Did you try comparing the file list?

    I have seen 3 different people get this error and all of them were using windows 11. I'm beginning to think that might be the problem. According to this message, it should (maybe?) be fixed in 2023.1.0a26: https://forum.unity.com/threads/fai...s-error-meassage-on-windows-11-arm64.1383264/

    That specific issue you linked only affects ARM64 build option which was added in 2023.1.

    Generally, Failed To Load Mono message means that for whatever reason mono-2.0-bwgc.dll failed to load. That could include incomplete game download, AV software flagging it (unlikely, since it's signed) or not a full build being packaged. Does this happen to only very few people in your case, while using the exact same download?
