UE5.0 and UE5-main build ok but fail on startup

Hi,

Yes i am agree, we should do not have to modify the source code, this is just a turnaround to at least open Unreal and see what new in it.
I am definitely not confident to do something more serious with a build obligate me to comment part of the code, this can have snow ball effects etc…

So, what steps a did.
I build it on Windows, and i don’t do nothing special.
I do the same as i was doing on previous build in november and before.
It is the first time i get this errors.

Exemple from fresh git clone :

  • Run the Setup.bat file
  • Run the GenerateProjectFiles.bat file
  • Open the UE5.sln with VS19
  • I dont change nothing just right click on Engine → UE5 and select Generate

Wait the compilation which is success without warnings or errors.
Thast it, then run the Engine → Binaries → Win64 → UnrealEditor.exe

And i get the errors listed in this post.
