Version up Compile error

I build and compile 4.25 version’s code, there’ no problem. hot reload successs.
Next, I version up that project to 4.26 version, and then I was recommended to open the copy one.
But there was problem. Compile Failed windows show up with numerous errors.
On the Visual Studio, There’s no grammer errors. But always compile errors.
Unreal Engine bug report window is like down below.
Please Help me.

프로젝트를 컴파일할 수 없었습니다. Visual Studio 에서 여시겠습니까?( You cannot compile the project. could you open it on Visual Studio? )
