can not compile with il2cpp for any platform

Hello,

recently i wanted to make some tests how my client behaves when i compile it with il2cpp to convert it to a native C++ binary.

sadly tho, this approach failed brutally. i first thought it might be related to my System.Reflection code in one of my libraries i wrote, but even if i exclude this from the release version of the DLL via preprocessors, the error remains.

i can not build my app for any platform with il2cpp. as an example i post here the error message i get when i try to compile it with macos on macos big sur.

what i am pretty confused about is the fact that he tries to execute il2cpp.exe on my macos o.o

i hope someone can help me with this issue....

Thanks in Advance

 

Addition Note:
if i use 2020.2.xf it works and i can compile the project. so i guess it is an issue with unity or il2cpp of that unity version :/
