the reason of error is what i choose the hybirdclr/ generate/all 

Hi, we don't know HybridCLR. But it seems that it makes changes to Unitys il2cpp code. Our ikcalculator is encrypted and this might be the reason that there are issues. Might be very difficult on our side to support HybridCLR which is a very special setup.
