Assertion error when building a development project

Game works fine in editor, but i get an Assertion failed: SchemaIt != SchemaEnd [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Serialization\UnversionedPropertySerialization.cpp] [Line: 706] when building a project.
Tried to find source of problem in log, no luck. As plugins i manually installed only MotionWarping (lots of others like FastBuild Controller i’ve never installed myself, i suppose they probably are installed by default)

Strange part of log file:

After doing some of my favourite types of debugging - deleting everything one by one and then rebuilding i found out that game won’t compile with my character blueprint (which is pretty huge to debug the same way) and with the HUD class. Unreal doesn’t really provide any useful info to work with or i’m just not educated enough to find solution. Any help?

there is issue with some of ur structs

If ur using blueprint struct, i recommend u to use cpp and intialize it or delete and create same strcut in bp
