Missing precompiled package 'Zen'

I am trying to package my project for windows desktop. It worked fine before and I haven’t added any new plugins afaik, but now after working on it for awhile I am getting this error:

Missing precompiled manifest for ‘Zen’, ‘C:\Program Files\Epic Games\UE_5.1\Engine\Intermediate\Build\Win64\UnrealGame\Shipping\Zen\Zen.precompiled’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in Zen.build.cs to override. If part of a plugin, also check if its ‘Type’ is correct.

What the heck is ‘Zen’ and how do I fix it?

Is it the Zen mode plugin, perchance?..

I just tested this, and packaging is fine. It’s an editor only plugin.

I dont know, at least I am not sure. It’s located in:
UE_5.0\Engine\Source\Developer\Zen

I definitely didn’t install it manually. Also I don’t see anything ‘Zen’ in in engine Plugins window.

Ah… it’s the Zen loader. I’m afraid I don’t know what the problem is…

If you downloaded the engine, I guess you could try verifying it, in the launcher.

I’ve figured it out.

Apparently Zen module is referenced by DerivedDataCache module, which somehow got added to my .Build.cs file. However this module is developer-only and does not get packaged into shipping build.

Removing DerivedDataCache from Build.cs fixed it for me:

// remove this
//PrivateDependencyModuleNames.AddRange(new string[] {
//    "DerivedDataCache"
//});
