Nativization Fatal Error

When i nativizate my project as inclusive. After building the game, And when i start the game pop ups error and it say your game has crashed and it just only says Fatal error! And also when i nativizate with exclusive an one actor i get same error. Just Fatal Error.
Why ?

I looked the backup txt.
