UI animations cause nativized builds to crash.

If you cook a fully nativized build of your game and have any UI animations, it will cook with no errors or warnings but trying to play the game will crash with the following error.


Deleting the animation and cooking again works perfectly. Although I saw several other issues like this, none had this specific error message and most could not be easily reproduced in 4.17.2, so I also made a very tiny project that reproduces the crash.


Hello blobdole,

I ran a few tests with the project that was provided. I was able to reproduce the issue in 4.17. However, the issue appears to have been resolved in 4.18. I upgraded the project to the current preview (4.18 preview 4) and the issue no longer occurred. I hope that this information helps.

Make it a great day
