Packaging for Windows takes forever

My 13.9 GB project is taking hours since I converted it from 4.17.2 to 4.20.3
And it logs all kinds of files I never saw it log before in the Output log pane, such as Module.Engine.7_of_38.cpp

What’s up with that?

Is it because I’m using a source code compile of the engine?
I cloned 4.20 off GitHub 3 days ago. It took about 3 days of mostly waiting around for things to compile, to get it built after I switched the 0 to a 1 in Showflags.cpp to enable emissive bloom in splitscreen (which is the only reason I’m building from source), and then to convert my project to that version of the engine.

Now it looks like it’s going over all the same engine source files again just to build my game project to Win64.
If that’s what it’s doing, how to I make it stop and just build my game instead and not the whole engine? (I’m starting the build from the Editor which HOORAY does run fine and play in editor confirms that my game runs great and the emissive bloom works in splitscreen YAY!)

But am I going to have to wait 12 hours every time I want to package a dev build EXE of my game from now on?
Back in the epic launcher version of Unreal editor 4.17.2 I didn’t have to wait THIS long. Only about 10 or 20 mins.

Granted, I have 8 GB RAM and a Intel i7 sandy bridge processor but this seems ridiculous especially after it took only 10 mins or so and now it’s still going after 45 mins and it’s acting like when Visual Studio 2017 took 8-12 hours to compile the entire engine. If it’s compiling the entire engine how do I get it to stop?
Is it doing that just because this is the first time I’m building Win64 for this project?

Do you have “Full Rebuild” unchecked in your project settings?

Oh wow you answered quick but I didn’t notice until now.
I checked and no, Full Rebuild is not ticked. It’s unchecked.

I just added the Output and Message logs to this post. It took more than 3 hours to package the game and it failed.

Sorry mate, I’ve never seen this error before. No idea how to solve…

It’s all right. I guess it just takes a very long time the first time (quarter of a workday), and will continue to take that long until the first fully successful build. Once that has happened though, and if not aet to Full Rebuild, subsequent builds are much faster! 2-3 mins!

Just had to resolve a project setting to use Linear Alpha.

Thanks everyone who looked into it for me.
