Good afternoon, when trying to compile a ready-made project, I get the error “AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure” Tell me what this is about, I will attach the full logs below
Hello there @oklekela!
Thank you for sending the full log. After reviewing it, and checking through the community for information on similar cases, there are a few elements likely to be crashing the compile process.
The log contains calls to missing assets, as well as blueprint errors, like /Game/Cinematic/NewLevelSequence , BP_FirstPersonCharacter and BP_Weapon_Component, so the first step would be to check your project for any broken references, and recompile your blueprints.
After performing that check, please delete the contents for Saved, Intermediate, and DerivedDataCache folder, then attempt to compile the project again. Additionaly, if your project has world partition enabled, please save all your levels, and check for any warnings.
If the issue persists, try removing any plugins you have recently added to UE, and perform a cook test in an empty project, to ensure the issue not related to your engine install.
Overall, your scenario does not have a clear cultrip, so further investigation may be required. You can find additional steps to test in the thread below. Hope this helps!
