It has to do with the header files. Either Visual Studio did not finish parsing all of the header files or the PCHs are missing somehow…
This is my last straw unfortunately:
- In UE, go to Edit → Editor Settings → Source Code → pick “Visual Studio 2022” instead of “Visual Studio”
- Generate Project Files from .uproject context menu in Explorer.
- Wait for VS to index header files
- PROFIT???
- If not, do a Clean build in VS then repeat step 2 til 4
