Problem: UE launches the Unreal Project Browser instead of the project when I start it from visual studio (in debug mode)

UE launches the Unreal Project Browser instead of opening the project when I start it from visual studio (in debug mode).
I selected “DebugGame Editor” and “Win64”. This used to work to debug my project. But now it does not launch my project anymore, it opens the Unreal Project Browser instead. Why??!

I don’t know why this happened, but I solved the problem by launching the project from the .uproject file, and by regenerating the visual studio project in UE4 editor. (Note that in visual studio it’s always possible to attach a debug session to a running project)

I have the same problem and regenerating does not help, Also cannot attach. Any ideas?

Attaching worked after changing Attach to yes under debugging from project properties.

I had the same problem. The splash screen shows it is loading the project, but once finished, it shows the project browser. I finally resolved, but do not know which action is effective.

  1. Terminate all editor processes before clicking run button of VS. Some editor processes do not have a visible window.
  2. Add the absolute uproject file path to the debugger “Command Arguments” field. I do not know what will happen if I use the relative path.
  3. Add the “-debug” switch to the debugger “Command Arguments” field.

To start the editor directly, in the project browser select the below checkbox in unreal project browser:

and start the project, next time you start from visual studio (or any other IDE) it will directly open the editor.
