Today this error appeared when trying to compile.
Was there an engine update today?
Because yesterday this problem did not exist.
There is no problem when compiling from the command line
There is also no problem if I compile with Rider
Anyway. Can someone share the file (LiveCoding.json) with me?
Maybe if I put it where it is needed the problem will be fixed.
Thank you so much!!
I compared the files of version 3.0.3 against version 5.1.1…
I notice that the modules and libraries have not been generated.
Version 3.0.3
version 5.1.1
I disabled some plugins but it didn’t help to fix the problem.
I think this is correct as well…
I disabled live coding and now it compiles correctly from the Editor…
I don’t really know what happened… but I think an update broke the live coding or something…
So you never got Live Coding working? That’s not encouraging 
I’m having the same issue, and for two days now I’ve been scouring the web looking for a resolution, without any satisfaction.
I’m willing to just turn Live Coding off and fall back on the previous system just in order to get past this blocking issue for now, but that’s extremely unsatisfying.
EDIT
I actually just got it working by deleting the LiveCoding.json file in the Unreal Engine installation folder (C:\Program Files\Epic Games\UE_5.1\Engine\Intermediate) and letting UE rebuild it. I don’t know if that’s a suggested fix or not, so maybe make a backup before attempting it, but that’s what did the trick for me.
SECOND EDIT
Well, the “fix” I found above was apparently temporary as the problem is back after shutting down and restarting the Editor. It would appear that Live Coding is fundamentally broken and not ready for production
No, I never tried to use it again.
So far I haven’t needed to test code changes while the game is running.
Also discovered that live coding patches the executable.
Create a series of patches that sooner or later end up causing undefined behavior.
Your binary folder ends up filled with hundreds of useless patches.
In my case I am happier without the live coding.
But thank you very much for giving us your solution. It could be useful at some point.
Best regards!!
Now that UE 5.2 is up, does anyone checked if LiveCoding is still broken?
same thing happens on me today
Same Issue Here. Is there any solution?
Just do not use Live Coding (Disable it)
This answer was for you.
But for some inexplicable reason i sends it to someone else.
