How to debug engine source file without launch Editor?

My question is How to debug engine source file without launch Editor?
When I use “DebugGame_Editor” configuration to debug game, I can click stackframe to view it’s corresponding source file, both game and engine source file. But it will always launch editor.
Using “DebugGame” configuration to debug, I can only view corresponding game source file. When I click stackframe in engine, it says “source not available”.
I just want to view quickly debug engine and game source file without launching Editor.
Thanks!

I’d like to know as well as recently my dedicated GPU died but I continue to code until I get it replaced so being able to launch and debug would be very handy! I’m up-voting this.

To debug the engine you want to use the plain old “Debug” build configurations. The “DebugGame” set don’t do this so it’s much faster to build. So try “Debug Editor” and build that. Just be prepared to wait for quite a while.

Thank you for your reply.
I have read the official document, it says there are both “Debug” and “DebugGame” configuration. But I cannot find “Debug” build configuration in my project, only “DebugGame”(DebugGame, DebugGame_Editor). So how can I create a “Debug” configuration?

Hmm… I guess you need to get the engine source from Github and use that instead of the launcher version.
