Anyone can help me?

Anyone can help me?

Have you tried using the debugger in packaged game? There are tutorials for this. It's really not possible to guess what the problem is just from looking at some randomly generated callstack.

Also: If you have a reliable repro for this, please contact the development team with it.
Seems like it may be related to the engine itself.

I deleted the "Intermediate" folder, then repackaged the program, and the crash problem seems to have disappeared.
