Can't Open C++ when trying to start new project, but can open blueprint just fine

Development Programming & Scripting C++

I tried that and still did not work.

22

Wait, I allowed shadows.txt bc anti-virus would not allow it. I don’t know why this didn’t happen before. But when I allowed it it opened up. Now, for 4.27 unreal, is the opening page two chairs and a table for c++?

You right click and run it in admin mode by chance ? I Know It sounds dumb too ask lol but you never know

Many times.

I’m getting the same problems. I’ve tried all of the suggested solutions but nothing works. I’ve had nothing but bad luck with unreal engine. I’m starting to just think its a garbage fire of an engine.

Same Problem here in unreal 5.1

27

Same problem here in unreal 5.3.2, has anyone found a fix yet?

I just reinstalled UE5 and and installed the latest version (2022) of visual studio, and then it worked.

Delete “Postshot” plugin in Marketplace:
C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\Marketplace

Second Version: This has helped me too.
Copy project to external disk.
Deleting Intermidiate, Saved, binaries .vs and .sln project I then clicked on Generate visual studio project files. After that I also clicked on the Unreal Engine executable to run it and it requested to rebuild it which I allowed and the editor started.
After that I opened the visual studio solution.
When trying to then ctrl+F5 the project I had the encountered the Unable to start debugging error.
So setting my project (the one that is under Games in the Solution Explorer) to Set as Startup Project" solved it!
