Unreal not compile my character, why?

Hello all, unreal engine 4 not compile my character, why?

Try 1st save all then compile if is not work probabily is a bug. So try to open 1 other project copy all code and try to compyle in second project

Google Drive: Sign-in Preservation of all does not help.

I only have blueprints. Do I need to transfer my entire project? 15 GB…
This problem arose after I created the variable and pressed to compile…

I created a new project, migrated my character to a new project. My character is still not compiled

In a very strange way, but after a few days, my character was compiled … The problem is solved.
