same windows, same PC - It worked on 5.5.0, but it doesnt work on 5.5.4 ENGINE  
+installed MORE of this - everything from here:

known problem from 5.5.0

> From what I’ve seen the windows sdk configuration is probably fine. The memory is 32GB. The build was successful when I brought the files from github. Nothing else was done. If the build fails when you can start it in the editor, there may be some kind of bug. If the build fails even with ue5.4, this method cannot be used to resolve the issue. I heard that for 5.4 it’s a good idea to delete CitySampleCookedEditor.Target.cs.

saved files from 5.5.0 don’t work(I saved 3 working files), latest included from here are the same as from bellow ˘ and don’t work

$(EngineDir) = C:\Program Files\Epic\UE\_5.5\Engine

# copy file

$(EngineDir)\Plugins\Performance\AutomatedPerfTesting\Build\Scripts  
├──AutomatedPerfTestConfig.cs

STRANGE ERRORS - SAME ERRORS last time that worked in 5.5.0 were conected to these 3 files ubove ^

Hello there @2350lev!

Investigating around the community, I can confirm this is a known issue between the AutomatedPerfTesting plugin and UE 5.5.4.

Checking with my peers, the first step would be to ask if the plugin is needed 100% for your build, as disabling it during packaging would resolve the error. In case it is required, a possible workaround would be to backup its content, restore the version from 5.5.0, disabling file replace during buid, and try to pack the project again.
