Hello!
I’m posting this because I tried and failed after reading similar topics already existing in the forums.
My project is built with UE 5.3.1 source code.
After adding a new class in the Project Editor, I noticed that the Visual Studio 2022 window that popped up showed that the added class was there.
However, the live coding window said that compilation failed for the new class.
So I turned off the project and after a successful build in Visual Studio 2022, when I tried to reopen the project, it would always get stuck at 75%.
I’ve tried clearing the Binaries, DerivedDataCache, Intermediate, Saved folders and the .sln file, recreating the .snl file and building it, but the project still won’t open.
I also tried rebuilding from the snl file, which also failed.
I need several more new classes to complete the project and am desperate for help on how to resolve this issue. ;_;
The issue has been resolved!
The culprit was enabling UE5’s reinstancing feature.
You need to go to edit > editor preference > live coding > reinstancing enable and uncheck the box.
Then create a new C++ class in the editor, and turn off the editor.
It doesn’t matter whether the live coding window shows a successful or failed build.
Delete the Binaries, DerivedDataCache, Intermediate, Saved folders and the .sln file, recreate the .sln file, build, run the project and it should now run!
