    Build failure when building with IL2CPP to Windows. Mono works fine. Please help!

    Using Unity 2021.3.3f1 on a very old Window 10 Education Desktop (18362).

    Tried: reinstall Windows SDK; Deleting Library Folder; Reimport all assets. None worked.

    The failure seems to be related to a particular script in my project which you can see here. However I have no idea why this script is causing issue. It looks fine. If I create a fresh project that has this script it is able to be built without problem.

    Error message in console:

    Details for the first console error:

    Ok it is not that script. It is one of the functions in my code that uses that class as an out parameter. The C# function looks like this:

    Code (CSharp):
    1. [Server]
    2. public bool GetBattleUnitWithTag(
    3.             BattleUnitRelationTag tag,
    4.             out FixedSizeLinkedList<BattleUnit> lst
    5. )
    6. {
    7.             //businesslogic...
    8. }
    The 
    [Server]
    attribute (which comes from Mirror Networking plugin) when used with a function having 
    out
    parameter seems to confuse IL2CPP.

    I digged through the generated cpp code and found that IL2CPP decides that there are two 
    FixedSizeLinkedList<T>
    types (one is called 
    FixedSizeLinkedList_1_t3EAA698F222717A950BC3D871BB65D51F83F6B70
    another similarly looking type that starts with 
    FixedSizeLinkedList_1_t
    ) for some reason; hence the syntax complaint on Cpp side.

    Refactor the code to not using 
    out
    parameter, OR simply removing the 
    [Server]
    attribute (it is not essential for functionalities in my case) resolves the issue.
