1- Please add a description to your question, your answer make you look lazy, and that will discourage people from answering your question. Also feel free to add Hi and thank you.

2- Your images is not descriptive at all since most of the text is cropped. Also the red arrows are pointless

3- Please upload your error log files to this question so we can tell you what seems to be the issue

4- This text the engine showed you lets you know what the problem is, just find the lines that have errors and warning in them, and read them for more info on what is causing your compile error.

Hope this helps :slight_smile:

Hey nEmoTian,

Try opening a copy of your project in 4.13.1 and packaging it there. This appears to be similar to an issue in our database, UE-30993, that is fixed in 4.13.

If you are still experiencing the issue after upgrading, please provide the full log from your project’s Saved->Logs folder after the packaging fails.

Have a great day

Thanks for your help.And then,I will have a try.Thank you very much.
